Red Hat Bugzilla – Bug 431619
2.6.18-53.1.6.el5 has really bad NFS performance compared to 2.6.18-53.1.4.el5 or previous RHEL5 kernels
Last modified: 2008-02-07 09:47:33 EST
Description of problem:
Starting programs that are on an NFS (auto)mount or sourcing shell scripts that
are on an NFS (auto)mount take a very long time with the 2.6.18-53.1.6.el5
kernel. Downgrading to 2.6.18-53.1.4.el5 or any previous RHEL5 kernel fixes the
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Upgrade to kernel-2.6.18-53.1.6.el5
2. Time to open shells (user home dirs on NFS mounts) or open applications
residing on NFS mounts take a very long time.
3. Downgrading to kernel-2.6.18-53.1.4.el5 or kernel-2.6.18-8.el5 fixes the problem.
NFS performance is very slow
NFS performance should be same as or better than previous RHEL5 kernels.
> Version-Release number of selected component (if applicable):
^^^^ typo should be kernel-2.6.18-53.1.6.el5
