MySQL handling heavy loads

[T. Elsas]

Has anyone used MySQL in a public web site environment that receives 1
- 1.5 million sessions/day? Sessions are mostly content and light
commerce.

Site spikes to 3 million sessions/day about 4 times/year.

Trying to find a good example of MySQL holding up under this kind of
load.

Thanks!

Yes..
I have.. :)

0.5 milion in 3 hours (every week).

The best you can do is buy a very fast, dual (or more better) processor
decated system, lots of memory and remove as much overhead as possible.

You have to calculate the most buzziest time;

3 milion a day or...
1 milion in 4 hours and 2 in 20 hours.., or
what is the most buzziest minute?

, be more detailed on that for yourself.
And then try to get the connection+quer y time much below the avarage time
you have for one session in that minute.
It's not enough to get it at the avarage time you have for one session.

I belive mysql holding up to a large part (maybe 90%) would depend on
proper structuring of table indecis. Make sure thare are NO table
scans (of larger tables) in queries. This makes a tremendous
difference. Presuming you have root access, enable slow query log for
mysql (see mysql docs), and optimize every query that is hanging up
and not performing in subsecond.
