Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Im getting a lot of lag when NFS is accessed. The machines having this problem are all identical hardware. They are being served home directories via NFS. The problem does not seem to exist in 3.1-RELEASE. My initial build/install of 3.1-STABLE (3/15/99) did not have this problem. I upgraded an identical 3.1-RELEASE machine to stable and it also is having this problem. I see some changes have been committed. These machines work fine with -RELEASE, and we have an SMP machine running the lastest -STABLE without problems. Here I grab a file via ftp, downloading it to a local FS. 27533787 bytes received in 134.06 seconds (200.57 KB/s) Here is the results of the same file to an NFS mounted home directory. 27533787 bytes received in 712.78 seconds (37.72 KB/s) top during the above ftp session... ouch! last pid: 1327; load averages: 3.96, 3.25, 1.89 up 0+09:06:57 20:55:59 28 processes: 4 running, 24 sleeping CPU states: % user, % nice, % system, % interrupt, % idle Mem: 8072K Active, 30M Inact, 12M Wired, 4864K Cache, 7572K Buf, 6612K Free Swap: 200M Total, 200M Free PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 134 root 2 0 208K 28K RUN 6:16 72.31% 72.31% nfsiod 135 root 10 0 208K 28K nfsidl 1:49 15.04% 15.04% nfsiod 1313 root 45 0 1276K 844K RUN 0:37 5.52% 5.52% ftp 1326 root 41 0 1584K 820K RUN 0:03 5.46% 4.88% top Copyright (c) 1992-1999 FreeBSD Inc.
