slow read/writes to Samba share from Win98SE

[Jim Priest]

Recently setup Samba on a RH Linux 6.1 box at home - network is 100bT - and 
printing /browsing works great.

However reading or writing files of any size to the share seems overly 
slow.   For instance a simple 1MB PNG file takes 20-30 seconds to load 
up.  Of my local HD it's instant.

Any ideas what could be causing this? I read through quite a few docs to 
get this working to begin with :)  and didn't see a lot in regards to 
performance tuning...

thanks much!
