[Lustre-discuss] small file performance

[Aaron Knister]

For whatever reason, searching my lustre mount (ls -R or find),  
compiling code and other operations involving lots of small files are  
painfully slow. There is no load on the filesystem other than my  
various tests. I've disabled lnet debugging. Just to give you an idea  
of how slow it is-- a ./configure of this particular code on a local  
filesystem takes less than a minute. On lustre it's been running for  
five minutes and is hardly half way through. An untar on the local  
filesystem takes .9 seconds while that same untar takes 12 seconds to  
our lustre mount. Any ideas for improving this?
