What is the difference between "noac" and "actimeo=0" NFS mount options?
Issue
- What is the difference between the "
noac
" and "actimeo=0
" NFS mount options? - Our NFS performance suffers when using "
noac
", but performs quite well with "actimeo=0
", why is this? - Is NFS attribute caching broken in RHEL as per the upstream kernel commit b0b539?
Environment
- Red Hat Enterprise Linux 5
- NFS client
