Hi,

a "small tip" which can speed up the system if you are using mysql 4.x.

The "query cache" is turned off by default.

Turning on the cache boost up the system!

To have a look, if your caching is turned on / off:
mysql> SHOW VARIABLES LIKE '%query_cache%';
+-------------------+---------+
| Variable_name | Value |
+-------------------+---------+
| have_query_cache | YES |
| query_cache_limit | 1048576 |
| query_cache_size | 0 |
| query_cache_type | ON |
+-------------------+---------+
4 rows in set (0.06 sec)

If the "query_cache_size" is set to 0 -> the caching is disabled.

Just put this in your my.ini / my.cnf configuration file:

query-cache-type = 1
query-cache-size = 32M

Kind regards,
Emil.

Best wishes,
Georg.

Thanks for the tip! I'm running version 3.x, which doesn't have <i>query_cache_size</i>, but does have <i>query buffer size</i>, which I suspect is the same thing. I have a bit of investigating to do...

Out of curiosity, do you recommend shifting to 4.x?

good one, but watch your swap. If you swap to much your system will slow down
