Hi! All the select statements have indexes on appropriate fields. Mysql appears to run fast, I was just wondering if there was anyway to make it faster. It is currently running on Windows, I have also ported it to HP-UX 11. The queries are of the type : SELECT * FROM textl WHERE parsetext = "" and filter = "" GROUP BY code.

suggestions - server options/mysql variables
Hi! Does anyone know any mysql options I can change in the my.ini file or mysql variables to increase the speed of select statements? About database: -uses only select statements for queries -no transactions -if database becomes corrupt in anyway, not a big deal I can recreate it -it is a small database, I do not need recovery, raid or any other backup mechanism -queries generally return very little data I will test any suggestions people have for me.
