2Gb ram var sunucumda. my-huge.cnf kullandım.
top -n1 :
Mem: 2066928k total, 2006800k used, 60128k free, 13300k buffers
Swap: 2031608k total, 1002292k used, 1029316k free, 214480k cached
My-huge.cnf i kullanmadan önce %60larda seyreden ram seviyesi , kullandıktan sonra %80in altına inmedi. Ayrıca swap ta yüksek.
Sunucum için my.cnf değerleri ne olmalı

my-huge.cnf 16Gb RAM içındir oysa sizin sadece 2Gb nız var.
my.cnf inizi buraya eklerseniz yardımcı olmaya çalışırız.

# Example MySQL config file for very large systems.
#
# This is for a large system with memory of 1G-2G where the system runs mainly
# MySQL.
#
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /var/lib/mysql) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
# The following options will be passed to all MySQL clients
[client]
#password = your_password
port = 3306
socket = /var/lib/mysql/mysql.sock
# Here follows entries for some specific programs
# The MySQL server

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted

# to the master - required

mysql optimizastonu için tuning-primer.sh scriptini indirmenizi öneririm.
ssh de çalıştırabileceğiniz bu script mysql ayarlarınızı kontrol edip tavsiyede bulunuyor.

Innodb uzerinde calismalarim devam ettigi icin henuz tavsiyede bulunmuyorum. Burayi takip etmeye devam edin. Sonuclari alinca innodb ye de girecegim.
teşekkür ederim. yarın öğlene doğru siteler taşınmış olacak, dediğiniz gibi makine işler duruma geçtikten sonra yeniden yazarım gidişatı ve bahsettiğiniz yazılımın önerilerini.
bu arada, plesk panelli serverlarda skip-innodb eklenince panel açılmıyor. verdiğiniz confdan skip-innodb yi çıkartmak zorunda kaldım.
