2.07 Upgraded 2.2.0 SLOW

[Chill]

I just upgraded to 2.2.0 from 2.0.7, my samba server was running
perfectly, file transfers were fast, printing was working fine.  Once I
upgraded it takes for ever to transfer files.  I noticed that in the Samba
PDC 2.2.0 FAQ they had share modes = no, is this required ? Basically
Samba is my PDC, and i have multiple win9x clients.  Also, when trying to
run a dos based paging system from a smb share it takes about 5 min. to
load, before it took seconds.  Any ideas ?

Here is my SMB.CONF
