#3963 — About scalability...

Hello,

I have come to an interresting subject, i have tested
my Parallel archiver that is using parallel compression
and it is scaling but not perfectly, so why database
engines and hahstables are not scalable, since they are disk bound
or/and memory bound and your Parallel archiver is scaling but
not linearly and perfectly ? cause you have to understand
that parallel compression can be expensive, it's the compression
that is expensive and that can scale on multicores, but the memory data
tranfers are not scalable, it's the same for game engines
they will not gain on scalabilty on memory transfers , but
on rendering or compression or something like that that scales
on multicores, mathematic algorithms that dont use big memory data
transfers can scale also on multicores, but database engines
and hashtables are memory bound or/and disk bound etc. so they
are not scalable on multicores.


Hope you have understood my ideas...


Thank you,
Amine Moulay Ramdane.
