Here are some results I have for data transfer speeds across a network with a variety of hardware. I'm afraid its in Dokuwiki internal text format but it's fairly understandable I think (an advantage of Dokuwiki):- ======Speed Tests====== These were done when I got a new 3Tb disk for backups to investigate the relative speeds of copying files across the network. All the tests were done __from__ //chris// to the named destination. The //cp// column is for copying to an nfs mount, or in the case of //chris// to a local filesystem. Similarly for the //rsync to nfs// column for destination //chris// the copy is to a local filesystem. The USB 2.0 disk was in all cases my 750Gb eSata/USB drive with ext3 filesystem except for one set of tests to raspberrypi with NTFS filesystem. ^ Destination ^ Hardware ^ Disk drive ^ Connection ^ Bandwidth ^ cp ^ rsync to nfs ^ rsync direct ^ rsync daemon ^ comments ^ | acer-aspire | Intel Atom | Internal | 100Mbs | 94 Mb/s | 11.4 MB/s | 10.8 MB/s | 11.3 Mb/s | | Limited wholly by connection speed | | ::: | ::: | ::: | WiFi | 22 Mb/s | 2.7 MB/s | 2.6 MB/s | 2.8 Mb/s | | ::: | | ::: | ::: | USB 2.0 | 100Mbs | 94 Mb/s | 11.6 MB/s | 10.4 MB/s | 11.1 Mb/s | | ::: | | ::: | ::: | ::: | WiFi | 22 Mb/s | 2.6 MB/s | 2.6 MB/s | 2.8 Mb/s | | ::: | | chris | Intel I3 | Sata II | Same drive | 3000 Mb/s | 108.1 MB/s | 63.9 MB/s | 71.4 MB/s | | | | ::: | ::: | ::: | Other drive | ::: | 357.1 MB/s | 61.0 MB/s | 121.6 MB/s | | ::: | | backup | WD My Cloud | Internal | 1000Mb/s | 346 Mb/s | 10.4 MB/s | 9.6 MB/s | 1.4 MB/s | | Mostly limited by processor speed | | ::: | ::: | USB 2.0 | ::: | ::: | 8.7 MB/s | 8.3 MB/s | 1.4 MB/s | | ::: | | beaglebone | Arm | SD Memory | 100Mb/s | 94Mb/s | 7.6 MB/s | 7.3 MB/s | 8.0 MB/s | | Mostly limited by connection speed | | ::: | ::: | USB 2.0 ext3 | ::: | ::: | 10.8 MB/s | 10.7 MB/s | 4.2 MB/s | | ::: | | D-Link NAS | Arm | Sata II | 1000Mb/s | | 37.9MB/s | 37.0 MB/s | 4.6 MB/s | 21.2MB/s | | | raspberrypi | Arm | USB 2.0 NTFS | 100Mb/s | 92 Mb/s | 2.4 MB/s | 2.5 MB/s | 1.8 MB/s | | | | ::: | ::: | USB 2.0 ext3 | ::: | ::: | 7.9 MB/s | 5.4 MB/s | 3.6 MB/s | | ::: | | revo | Intel Atom | Internal | 1000Mb/s | 911 Mb/s | 50.7 MB/s | 38.7 MB/s | 10.6 MB/s | | Processor limited but quite good | | ::: | ::: | USB 2.0 | ::: | ::: | 28.9 MB/s | 25.0 MB/s | 10.8 MB/s | | ::: | | ::: | ::: | eSata | ::: | ::: | 51.9 MB/s | 45.8 MB/s | 10.7 MB/s | | ::: | | test | Intel quad | Internal | 1000Mb/s | 850 Mb/s | 80.3 MB/s | 56.3 MB/s | 66.4 MB/s | | | | ::: | ::: | USB 2.0 †† | ::: | ::: | 84.6 MB/s | 46.5 MB/s | 44.2 MB/s | | ::: | | ::: | ::: | eSata | ::: | ::: | 79.6 MB/s | 52.8 MB/s | 69.7 MB/s | | | | vigor | Router USB | USB 2.0 | 1000Mb/s | | | | | | | †† Results for the USB 2.0 drive on the //test// machine were **very** variable, by a factor of up to 3:1 between best and worst cases, I've listed about the best speeds obtained. -- Chris Green ·
