Sami,
I run Fedora core 1 and haven't had any problems.
This is all you do if you want MySQL 4.1.1.
wget

SCSI, 15,000 RPM drives and a decent amount of memory 2-16 gigs. Dual procs
definitely do help; we have tried it with dual procs with hyperthreading and
without and with hyperthreading seems to be much faster.
Besides that, you can run it on any OS; we use Fedora, with Linux 2.6.x.
But that's
Chris,
You would have to send the table structures including any indexes and also
the real queries.
It would also help if you would send an explain on your select statements.
100+ a minute is not much, I have one server currently doing:
Queries per second avg: 3157.235
Yes, that's per second,
Personally, it's an unexpected flaw that I hope one day will be fixed. But
I'm not holding my breath, even though they seem to be planning for it. But
it could also be because of query-cache.
To benchmark something like this, you really need to add SQL_NO_CACHE to
your select statement to get
I've got a server with 24 gigs in it and it works just fine. About 3 with 8
gigs and a few with 2 gigs. All running 4.1.1. And all of them run without
any problems on Xeon's with Hyperthreading.

Donny-
While I appreciate your bluntness, I did have this issue a time back with
4.1.x.
In your email, the reference to big-tables stated
I'd never actually tried that before, it definitely seems like a bug to me.
SELECT *
FROM WordScoreTemp
WHERE word = (
SELECT word
FROM Word
WHERE word = 'mysql' )
The above works fine.
SELECT *
FROM WordScoreTemp
WHERE word = (
SELECT word
FROM Word
WHERE word = 'mysql' ) order by score;
Chris,
Is it faster if you remove the 'IS NOT NULL'? I know that's not the results
you want, but we have found that is NOT NULL will do a full scan. But we
normally use it with a join. Since you are using one table, I'm not sure
how it would affect it.

Hi Donny,
What server hardware do you use to support 24G RAM over 32-bits limit?
