MySQL is already a multithreaded process, even though you only see a single
process. Note that it doesn't scale very well above eight or so cores,
especially InnoDB iirc.

single query over multiple cores for faster
Hi Johan,
Thanks for the quick response.
Is there any command available in mysql using which I can check how much
CPU is being used by each mysql thread. Or any article where how mysql
multi-threading works.

the command 'top -H' will show you the individual threads with their CPU
use, but I'm afraid I don't know how to link that up with a MySQL 'show

Hi all,
We have a copy of an old version of a database and a huge LOG file ( 9
Gig ) ( not the binary log unfortunately but the GENERAL QUERY LOG )
started when we put this database live.
The only solution I see would be to run the queries from this log file
to the database. What do you think?
I've also checked the error log and there isn't anything that indicates
where these aborted_client connections are coming from. I checked today and
I have 100 more of these.

I used phpMyAdmin to look at the stats for my MySQL server.
here's what they show...
http://www.2-bit-toys.com/db_info/server_status.html

and 'Aborted.'
When would these situations occur? Is it normal to see these?

I just issued a show status query and the numbers are what MySQL returns.
Strange.
Failed attempts (aka aborted_clients) : 8154
Aborted (aka Aborted_connects): 319
Total (aka Connections) : 4626
So phpMyAdmin is basing the % calculations on these numbers, that's why we
see the weird percentage.
