Well, 10 million rows is not that many when it comes to an enterprise level
Database. Bad or poor performance could be down to many things:
Over indexing
Bad Database design
Poor logic and SQL blocks
One thing to try is see how fast queries return and execute locally via SQL
rather than via CF/HTTP. If it fast etc perhaps its front end code causing

Another suggestion that has worked for me in a previous company where we handled millions of rows of family tree data was archive tables and de-normalisation (it was Oracle not MySQL though).

ie anything over 12 months old can go into an archive table then your common queries (within last 12 months) will search a table with less rows.

How busy is the server? Could you schedule the reports to be done at a
time that it's not being hit so much?

@James
I couldn't agree more - shifting relevant processing to the db is a
great idea.

@Gareth
After reading that article on mysqlperformanceblog.com I am looking at
these things just now:
. Re-designing query sql
. Re-designing your application
. Caching - !! need to experiment with this for sure but I don't

I don't know how feasible it is but on top of what Gareth is saying we
actually found a large performance benefit in shifting the reporting
over to the actual DB itself. Whether that be creating stored procedures
for dealing with the backend process and handing it across to CF that OR
using a Third Party tool for the reporting completely (again dependings

Hi Martin,
There's loads of things you could do to speed up performance, but it's
very hard to say here what will help. Every setup and application is
different, and what works for one, may have an adverse affect for
another.
If this is a major problem, and your budget permits, then it may be
worth getting a specialist consultant in. Alternatively, you just have

There was some optimisation done before I started, especially
'indexing' to speed up queries, some of the heavy lifting like spatial
queries have been removed to Oracle express, even so I still get 'time-
out' reports on a daily basis so I keen to find out how I can improve
things.

I'd like to learn more about replication, working with datasets in

Just wondering if anybody has any expertise working with large MySql
data sets OR knows of any good resources for this.
I'm just looking to improve my own skills as I have one table with
over 10 million rows now.
