However there is a patch to make linux cache those ACCESS checks in order to reduce the number of RPC calls. It has a very noticable effect if you are running as root (for which the current algorithm is very inefficient). IOW: you have 3 obvious solutions. 1) Use NFSv2... 2) You could backport the ACCESS caching patch http://www.fys.uio.no/~trondmy/src/2.4.19/linux-2.4.19-21-access.dif to RedHat's 2.4.18 kernel. 3) Upgrade to the RedHat 2.4.20 errata kernel, and apply the ACCESS caching patch for 2.4.20 to that. Alternatively, RedHat may already have applied the ACCESS patch in their rawhide kernels? Perhaps Steve Dickson could comment on that?
