Hello ,

I running dedicated server for 2 web sites which those 2 web sites are in high load.

I use linux centos version 4 and mysql version 4.1.18 std

currently I don't use any option file which need to be located under :

/etc

I would like to use option file but I don't know which one to use ?

The specification of the server is :

Intel Pentium 4 3000 MHZ with 2 MB cache memory (model 630)
2 GB of ram memory (DDR SDRAM 400 MHZ non ECC non REG)
160 GB under raid 1 (mirror) SATA 7200 RPM with 8 MB cache memory

The problem is that I host only 2 web site under this server and there is very high load. There are alot's of visitors every day.
also there is 1 database which the capacity is 1.2 GB

so , about the option file , There are the follwing files , which one do recommend me to use as basis configuration option file ?

my-huge.cnf
my-innodb-heavy-4G.cnf
my-large.cnf
my-medium.cnf
my-small.cnf

The storage engine of the database is : MyIsam
I can't move to InnoDB because I use IPB forum board which use MyISAM only to the best of my knowledge .

also I show the status of the mysql server under load minute :
