I am trying to push the performance of a Mysql database a little more,
it's pretty busy, but I hope to squeeze a tad more out of it.
I am a newbie/pretty clueless wrt MySQL in general, so ...
I run the status command, and see the following.
mysql Ver 12.20 Distrib 4.0.13, for pc-linux (i686)
Connection id: 27840031 Current database: Current user: [EMAIL PROTECTED] SSL: Not in use Current pager: stdout Using outfile: '' Server version: 4.0.13-log Protocol version: 10 Connection: Localhost via UNIX socket Client characterset: latin1 Server characterset: latin1 UNIX socket: /var/lib/mysql/mysql.sock Uptime: 4 days 14 hours 26 min 56 sec
Threads: 161 Questions: 128065100 Slow queries: 0 Opens: 657 Flush tables: 1 Open tables: 512 Queries per second avg: 322.082
----
The value for Open Tables is 512, which looks suspiciously to me like
it's hit a limit. Is there a way to increase that limit? Or am I
misunderstanding what status is telling me?
I have partially answered my own question, the Open Tables number looks
like a limit, but I am not sure I am hitting it.
Some digging around has shown that one table of the database in question
on this machine, is getting beaucoup writes, about 10 mil/day. It is a
MyISAM table, and locking for the writes may be the bottleneck.
So my question is, how can I improve this? any suggestions of things to
try, or paths to take?
