Hi.
I am using Win98SE on a P3 450.
Sambar Server V5.0b1 with PHP 4.04.
ODBC to MS SQL V7 on a 10mb LAN.
Speed is VERY good.
What datasource are you connecting to?
If you are using a Windows system, rather than a *ix, try using the same query in something like MS Query.
I have found the speed a little slow for Access Databases via ODBC, but they DO work.
