Fri Dec 12 12:23:54 2008 guru - Ticket created I am attaching the result of an experiment I did based on Avati's request. I have tabulated the times taken for the three commands: cp -a /usr . du -hs usr find . -type f | xargs cat > /dev/null The server had posix and posix-locks. The client had one afr over two servers (in case of AFR) or just a protocol client (in case of point-to-point). The client in all the cases was being run on a different machine than the servers. The backends were cleaned each time. Note that I did the exercise for IB and TCP. All timings in Seconds cp du find | cat AFR TCP 892.16 92.72 721.48 AFR IB 604.56 96.62 231.47 P2P TCP 399.04 33.77 400.79 P2P IB 337.79 26.14 129.65 -------------------------------------------------------------------------------- # Tue Apr 07 18:17:17 2009 gowda - Correspondence added avati, why was this test recommended? what was the conclusion of the test? did any of the enhancement, bug-fix, performance optimization that went into glusterfs depend on this test? if yes, please update the ticket with the details (or overview) of the changes that went into glusterfs as a result of this test. -- gowda
Test was run on an old version of GlusterFS and hence no longer meaningful.
