Description:
Hi,
We are continuously facing performance issue in our existing MYSQL db server. It using Innodb table space. Database current size is 1.5 GB.
Existing RAM on server is 3 GB and 2.5 GHz - 32 bit
We are planning to move 64 bit platform and increasing memory to 7.5 GB and 2.5 GHz dual core
Following are current my.cnf settings. Could someone please guide me to set new value in my.cnf according to 64 bit 7.5 GB RAM.
