After fighting with the nfs invalidation logic for a while, I'm finally starting to get decent read speed from the cache. Here's a quick comparison of results:
-------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU old nfs 10 1487 30.2 2235 6.5 1113 9.7 1768 32.3 2479 17.7 535.5 19.5 new nfs 7 1551 33.8 2185 5.2 2278 10.5 6078 90.7 40438 95.9 1394.2 25.1
(I changed the file size because I'm running the nfs server on the local machine, and don't have enough memory for two copies of a 10M file in page cache.)
The code still needs a little polishing, so I'll wait until 2.1.58 comes out to issue a patch.
Regards, Bill
