It applies to the number of significant digits. For 1234.50, 6 is needed.</div><div></div><div>For 1_500_000_000.100, 13 is needed to keep the number as is.</div><div></div><div>So the precision might suffer when you had a precision of 10 and counted billions of Czech Korunas.</div><div></div><div>Still, a precision of, say, 1000, is way faster than unlimited precision (which is I think the default).</div><div></div><div></div><div>Hi there, we had to do a 16TB volume restore job for a Veeam Agent server that took several days to complete, even though the throughput between the backup repository and target server is enough to have done that job in about a day. I have 10GB network connectivity between servers, and, the servers are both running Storage Spaces with tiered storage (SSDs for data ingest), and we've done tests outside of Veeam and we can usually get between 300-500MB/s on this setup. It was crawling along at like 30MB/s. During the restore, I was watching Performance Monitor counters and there wasn't a ton of disk activity on the target server, the network, or even that much read activity on the backup repository. I'm wondering now if the issue is due to fast cloned synthetic full backups. The most recent full backup was almost a week old (with 3 VIBs in between), but there are like 5 other VBK files on that volume that were all created using ReFS fast clone. In my mind, it makes sense that this could be the issue, because during the restore job, it has to read the fast cloned VBK, see that the blocks reside in another file, and jump to that file instead. However, I don't have a good way to prove that. Has anyone else had performance issues restoring large backups from a backup chain with multiple fast cloned VBKs? Is there something more obvious I should be looking at?</div><div></div><div></div><div>On the one hand, it is hard to design metrics that accurately represent the user experience. On the other hand, it is difficult to make metrics that are usefully precise. As a result, many teams cannot trust their performance data.</div><div></div><div></div><div>Even with accurate and precise metrics, the data is hard to use. How do we define "fast"? How do we balance speed and consistency? How do we quickly find regressions or see the impact of optimizations?</div><div></div><div></div><div>While performance.now() is clearly the better clock to use, it is not perfect. They both suffer from the same issue when the machine is asleep: the measurements include the time when the machine was not even active.</div><div></div><div></div><div></div><div></div><div></div><div></div><div>Fortunately, there is an easy solution. If there is a current event, instead of using performance.now() (the time we see the event), we use window.event.timeStamp (the time the system logged the event).</div><div></div><div></div><div>It shows a period where performance regressed, and was later fixed. It is hard to spot the regression if you look only at the 100ms results (the top of the blue bars). It is easy to spot if you look at the 50ms results (the top of the green bars).</div><div></div><div></div><div>The Performance Indicators dashboard, which will be updated monthly, provides a statistical snapshot of the fast-ferry program in the Overview tab and sailing-by-sailing details on the Bremerton and Kingston tabs. The dashboard answers common questions like these:</div><div></div><div></div><div>Golang is considered one of the fastest-compiling languages in the world. Tech companies like Google, Uber, and Twitch love using it and rely on it for their in-house development. It was considered one of the most popular languages of 2021, according to Stack Overflow. Golang also had one of the highest developer adoption rates of 2021.</div><div></div><div></div><div>Golang is much faster than Java in terms of performance and speed. Since Java is compiled on a virtual machine, its code must be changed to bytecode before passing through the compiler. Even though this step makes it a platform-independent language, it significantly slows down the compilation process.</div><div></div><div></div><div>Golang processing is faster and more lightweight than Node.js. Golang can also handle subroutines concurrently (i.e., it can execute threads in parallel). This is different from Node.js, which is single-threaded. This feature also improves the scalability of the final application.</div><div></div><div></div><div>In contrast, Golang only uses packages that are necessary to run the program. Golang has a feature that reminds the developer to remove unused packages from the final build. It throws a compilation error whenever it detects an unused variable or import, trading short-term convenience for performance and efficiency.</div><div></div><div></div><div>Goroutines are an inexpensive way of handling concurrency in Golang applications. However, they can have a significant memory footprint if not managed properly. Goroutine mismanagement can also lead to performance degradation.</div><div></div><div></div><div>You can optimize your system performance by making your I/O operation asynchronous. This can be done by utilizing multiple cores for I/O operations and using variables such as sync.WaitGroup for synchronization.</div><div></div><div></div><div>Golang is a very versatile and promising programming language. Many companies use it to optimize their product performance and improve their efficiency. Furthermore, due to its goroutines that handle concurrency issues, it is the perfect language for preventing scalability bottlenecks.</div><div></div><div></div><div>Golang allows developers to create performant and lightweight applications that are optimized for performance. Golang applications are easily maintainable and vastly outperform Node.js/Java-based applications in terms of performance. For microservices and enterprise cloud projects with a focus on performance, Golang is a great option.</div><div></div><div></div><div>To get the best tangible estimate, test your site with a free performance measuring tool like Website Grader. Just paste in your home page URL and see how your site performs. This tool and many others even provide speed suggestions which you can apply, then try again.</div><div></div><div></div><div>Like plugins, your active WordPress theme might be placing an unnecessary burden on your web server. Themes that are packed with high-quality images and effects might look cool, but they come at a cost. Fancy effects can require a lot of code, and many themes are programmed inefficiently, both of which inflate file sizes and slow your page performance.</div><div></div><div></div><div>Large images are another common culprit of slow WordPress websites. To further raise your site performance, reduce your image file sizes as much as possible without sacrificing quality. The goal is to save space but avoid making users squint to see your visuals.</div><div></div><div></div><div>Lazy loading gives the impression of a faster page load time because your content loads gradually, instead of requiring your browser to do all the loading work at once. Besides images, lazy loading can be applied to other media like video embeds, as well as other page content like text and comments. Check out our list of lazy loading image plugins to get started.</div><div></div><div></div><div>Or, if you prefer a slightly longer adventure, one filled with interesting nuggets of performance-focused data, consider skimming through the post, looking for the small code snippets and corresponding tables showing a wealth of measurable performance improvements. At that point, you, too, may walk away with your head held high and my thanks.</div><div></div><div></div><div>For each benchmark included in this write-up, you can then just copy and paste the code into this test class, and run the benchmarks. For example, to run a benchmark comparing performance on .NET 6 and .NET 7, do:</div><div></div><div></div><div>dotnet/runtime#70377 is another valuable improvement with dynamic PGO, which enables PGO to play nicely with loop cloning and invariant hoisting. To understand this better, a brief digression into what those are. Loop cloning is a mechanism the JIT employs to avoid various overheads in the fast path of a loop. Consider the Test method in this example:</div><div></div><div></div><div>For anyone familiar with generics and interested in performance, you may have heard the refrain that generic virtual methods are relatively expensive. They are, comparatively. For example on .NET 6, this code:</div><div></div><div></div><div>While this support is all primarily intended for external consumers, the core libraries do consume some of it internally. You can see how these APIs clean up consuming code even while maintaining performance in PRs like dotnet/runtime#68226 and dotnet/runtime#68183, which use the interfaces to deduplicate a bunch of LINQ code in Enumerable.Sum/Average/Min/Max. There are multiple overloads of these methods for int, long, float, double, and decimal. The GitHub summary of the diffs tells the story on how much code was able to be deleted:</div><div></div><div></div><div>Also related to BigInteger (and not just for really big ones), dotnet/runtime#35565 from sakno overhauled much of the internals of BigInteger to be based on spans rather than arrays. That in turn enabled a fair amount of use of stack allocation and slicing to avoid allocation overheads, while also improving reliability and safety by moving some code away from unsafe pointers to safe spans. The primary performance impact is visible in allocation numbers, and in particular for operations related to division.</div><div></div><div></div><div>Finally on the IndexOf front, as noted, a lot of time and energy over the years has gone into optimizing these methods. In previous releases, some of that energy has been in the form of using hardware intrinsics directly, e.g. having an SSE2 code path and an AVX2 code path and an AdvSimd code path. Now that we have Vector128 and Vector256, many such uses can be simplified (e.g. avoiding the duplication between an SSE2 implementation and an AdvSimd implementation) while still maintaining as good or even better performance and while automatically supporting vectorization on other platforms with their own intrinsics, like WebAssembly. dotnet/runtime#73481, dotnet/runtime#73556, dotnet/runtime#73368, dotnet/runtime#73364, dotnet/runtime#73064, and dotnet/runtime#73469 all contributed here, in some cases incurring meaningful throughput gains:</div><div></div><div></div><div>You can also see improvements in string.Format and StringBuilder.AppendFormat, as well as other helpers that layer on top of these (like TextWriter.AppendFormat). dotnet/runtime#69757 overhauls the core routines inside Format to avoid unnecessary bounds checking, favor expected cases, and generally clean up the implementation. It also, however, utilities IndexOfAny to search for the next interpolation hole that needs to be filled in, and if the non-hole-character to hole ratio is high (e.g. long format string with few holes), it can be way faster than before.</div><div></div><div> df19127ead</div>
