[Moosefs-users] bonnie++ test

[Fyodor U. <uf...@uf...>]

Hi!

I'm still not understand why bonnie++ "Sequental Outpet Char" and 
"Sequental Output rewrite" test show dramatically low results. May be 
anyone know about resolving this problem?

During the execution of this tests disk tps/bps, cpu, ethernet on 
chunk/meta servers not loaded. But results like:

Hi!

You need to remember that MooseFS is a network distributed file system and
such tests are not very practical. For example each write waits for success
confirmation from CS - it cannot be bypassed. 


Kind regards
Michal
