Hi Mike,
The architectures of the engines are radically different, so you can
expect different performance characteristics.
But the main differences and advantages will show in the future, as
the engines are developed further. I spoke about the future directions
of PBXT at the last
Hi,
I would like to develop a commercial application using MySQL Community
Server as database platform. Can I do this?
Thanks and regards.

Server Specs
1 Dual Core 2.6 Ghz
2GB Ram
Database Specs

Min 10 rows, Max 100 rows
Total size approx 2GB
My.cnf
[mysqld]
set-variable=local-infile=0
Jim,

That's a lot of data to return, make sure you factor in data load and
transfer time. You may try breaking your query into smaller parts and
recombining the results in a scripting language. If you are searching
on a range (i.e. date range), break the range into smaller parts and
run multiple
Right... and perhaps try MySQL Enterprise Monitor. A trial is available from
mysql.com. It may give you hints on your mysql.cnf.

All,
We're seeing a huge surge in our qps and I'd like to make sure we're
tuned as well as we can be. I'm wondering if I've got some variables
