samba - May 2005 - Emergency - Samba Performance Consultant Required (2 hours - $500)

Hello,

I am in need of a Samba Performance Consultant immediatley.
My box is just not fast enough, and I still have 8 business hours left.

Consultant should recommend:
- fastest Samba options for our setup
- fastest Linux kernel options / sysctl parameters
- fastest Windows client options / registry settings

I expect to pay $500 for 2 hours of your time.  You should be an expert.

Its 12:30 Eastern, and I've been suffering for a couple hours.
If someone can help me immediately, then please respond to my cell
phone 609-335-7103.

Network is all Gigabit Ethernet.

There are 10 Windows 2000 clients, that poll a public shared directory
for 60KB files, and read them off, no writing.

The Samba server is a Dell Poweredge 2650 Perc 3/DC with a RAID stripe
of 2 fast 144G drives.
