Hey guys, Attached is a small patch that increases ls and pvfs2-ls performance. It increases some #defines from 32/64 to 512.
I did not see any change for small directories, but listing speeds were increased up to 26% for large directories (100,000+ files). Long listing performance with ls and pvfs2-ls seem to be generally unchanged. The file system used is a 5 node SAN setup with HA running 271. Also attached are some specifics of the performance we saw. I did not include an increase for pvfs2-lsplus. Increasing its MAX_NUM_DIRENTS value resulted in crashing all of the file system servers a couple of times. Bart.
