[Samba] Really bad Read performance

[news.broadpark.no]

Running Samba 2.2.7, compiled with LDAP support. I'm suffering from really
poor read performance problems on the server. Write speed is fine (after
adding "interface = <ip of eth0>/24"), giving about 4.4 MB/s. However,
reading files from the samba shares is just not usable. Reading a large (34
MB) file from the server takes more than 3 minutes on a W2K Pro client.

NIC on both server and client is set to 100/FD.

I've tried changing "socket options = ...", but no settings I've come accoss
makes any difference.

Does anyone have any good ideas as to what I can do to fix this?
