Subject network server overhead
Date Sat, 21 Jul 2007 04:02:18 GMT
I ran a simple test of executing VALUES 1 using a prepared statement 
over the network server in auto-commit mode. 10.3 seemed to be the same 
performance as 10.2, maybe up to 4% slower. The 10.2 numbers for me were 
consistent, but the 10.3 numbers seemed to vary from 96% to 100% of the 
10.2 numbers.

I was actually surprised because I thought I seen some claims of much 
faster performance with 10.3 server.

I was getting around 1,630 transactions per second (each transaction is 
a VALUES 1 statement) on a 100Mbit network.

Did anyone make changes in 10.3 that they think would make this simple 
test improve, or is anyone working on reducing the basic overhead for 
client server? Are the nio changes intended to improve performance?
