We have a PC that accesses an NFS directory exported by another directory. Both PCs are OpenBSD 3.9-stable i386 GENERIC and use sk network interfaces directly connected to a 10/100 Cisco switch (with 100baseTX full-duplex).

The destination is a collection of mailboxes in maildir format, so it is not unusual that there are directories with a large number of file.

I noticed that sometimes the first PC has a very high load average (but with high idle CPU percentages). Now I have found that in this cases the PC is reading (probably to recalculate the quota file) large directories.

I have seen that it needs over a minute to do a simple "ls path | wc" of a directory with 50.000 files (with filenames of about 70 characters).

Is it normal???

Is there something I can do to increase the speed?


Thanks
