[Samba] smbd uses very high load on CPU

[Schoep, Grant at STORM]

The Server machine:
I have a Solaris 2.6 server(Ultra 2, 200mhz, 512megs, loads of disks(about
48 total drives hanging on this beast).

It is running Samba version 2.2.8.

Client machine: Win 2000

The problem:
	Compiling code via Visual C++, source files and all that fun stuff
are on a drive on the Solaris box, being accessed via Samba. On the server,
the CPU load for smbd when compiling goes up to around 60-80 percent. It
noticably slows down compilation. Examples

Code on Solaris server(over network): 20 minute build time
Code on Windows server(over network): 8 minute build time
Code locally on the PC: 7 minute build time.

Should it really be that slow off a Samba share? Could it be a config issue?
Are there any things that can be done to help this out some?

All machines are on a single 100meg Full duplex switch( and are 100 FD)
