The machines (both client and server) are idle other than the testing I'm doing and I'm doing only one test at a time at this point. I did not do plain 2.6.0-test9 yet, but here is 2.6.0-test6 and 2.6.0-test9-bk17: -- 2.6.0-test6 -- Client nfs v3: null getattr setattr lookup access readlink 0 0% 749 0% 0 0% 130 0% 251 0% 0 0% read write create mkdir symlink mknod 833 0% 178577 14% 24 0% 0 0% 0 0% 0 0% remove rmdir rename link readdir readdirplus 24 0% 0 0% 0 0% 0 0% 18 0% 1 0% fsstat fsinfo pathconf commit 0 0% 3 0% 0 0% 1024801 85% Client rpc stats: calls retrans authrefrsh 1205411 7 0 -- 2.6.0-test9-bk17 -- Client nfs v3: null getattr setattr lookup access readlink 0 0% 744 0% 0 0% 129 0% 252 0% 0 0% read write create mkdir symlink mknod 873 0% 178574 14% 24 0% 0 0% 0 0% 0 0% remove rmdir rename link readdir readdirplus 24 0% 0 0% 0 0% 0 0% 18 0% 0 0% fsstat fsinfo pathconf commit 0 0% 3 0% 0 0% 1023451 84% Client rpc stats: calls retrans authrefrsh 1204092 3 0 Thanks, -- Jason Holmes ------------------------------------------------------- This SF.Net email sponsored by: ApacheCon 2003, 16-19 November in Las Vegas.
