Very slow NFS

[Pafnoutios]

Here's what I'm doing:

I'm on my client machine, installing Baldur's Gate in Wine. All six CDs of data (including the expansion pack) are in Wine's C:\BaldursGate. Wine's C: drive is on my /home NFS share at /home/WineC. /home is on my server on an ext3 filesystem (FAT won't play nice with NFS). My /home FS is on a 2-device RAID1 array on /dev/sdb, a 300GB SATA drive.
The installation seems to be going at about 1MB/min, if that.
Both network cards are operating at 100BaseTX, full duplex, through my router/switch.
I suspect NFS to be the bottleneck for I have the following lines in my clients dmesg repeated incessantly:
lockd: cannot monitor 192.168.1.2
lockd: failed to monitor 192.168.1.2
192.168.1.2 is the static IP address of my server.
rpcinfo on each machine gives the following:
client ~ # rpcinfo -p server
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100003 2 udp 2049 nfs

100007 1 udp 804 ypbind
100007 2 tcp 807 ypbind
100007 1 tcp 807 ypbind
It seems that my client has more rpc channels open to my server than my server has open to my client.
Both machines are running Gentoo (x86 "stable" on the server and ~x86 "unstable" on the client). Here are the services running on each (yes, portmap is running on both, but it does take a considerable amount of time to load when the client boots)

How can I speed up my NFS?

Took me a bit, but I found it :)

Sweet. Thank you.
I bookmarked that and will try it after Baldur's Gate finishes installing this weekend. It's already on disk 2 of 5.

I've tweeked my NFS performance satisfactorally. Apparently, my problem is more with wine. My normal file throughput is what I would expect based on my 100Mb connection and assumed NFS overhead, but it's much slower from Windows programs running through wine. I'm especially noticing it during installation (right now it's Morrowind), because that involves a long stream of file copying.
Does everyone experience slower file throughputs with wine and I'm just noticing it more because I'm also running through NFS. Might it also have something to do with the fact that my wine C-drive folder is on an ext3 partition? Could something be misconfigured somewhere?
