<DIV><FONT face=Arial size=2><SPAN class=769264815-21052007>I'm troubleshooting
an ocfs2 performance problem where creating files in a directory containing
~180k files is taking significant time to complete. Sometimes
creating an empty file will take >100 seconds to complete. This is
a three node cluster. I'm currently running OCFS2 1.2.3-1. Are there
any changes in a recent version that may address this issue? What should I
look at to troubleshoot? The systems overall utilization is
low.</SPAN></FONT></DIV>
