Bernard, stop it! I found the problem! :-)
It was the SLOB allocator (http://lwn.net/Articles/157944/); it's more memory efficient than the default SLAB, but it seems that with this allocator rsync becomes very very slow... so better to use SLAB (in fact in the x86_64 config it is correctly enabled). Moreover I checked in the trunk the 2.6.16.2 kernel (for i386 only).. it has some fixes and I already did the work to properly configure it during the tests of today... Cheers, -Andrea PS I've also added a comment about SLOB/SLAB issue on wiki (http://wiki.sisuite.org/BOELupdate)! http://lwn.net/Articles/157944/ Bernard Li wrote: > I'd rather not downgrade the kernel at this point - hopefully newer > releases will fix this problem. > > rsync is currently at 2.6.7 (we're using 2.6.6), so after the svn > server is back up I will try to see if that helps at all... > > Cheers, > > Bernard > > P.S.
