Jim,
Retrieving 100,000 rows will always take some time. Do you really
need to return that many rows? Are you selecting just the columns you need?
What are the slow queries?

Greetings List,
We have a medium-large size database application which we are trying
to optimize and I have a few questions.

1 Dual Core 2.6 Ghz
2GB Ram
Database Specs

table_cache = 512
We are having trouble with certain queries which are returning
anywhere from 100000 - 300000 rows. Total query time is taking approx
1 - 2 mins depending on load. Is there anything in our conf file
which could improve our performance? Are there any hardware
recommendations that could help us improve the speed? Would more
memory help us? Any comments or recommendations are greatly
appreciated.
Thanks much.
