Formula for Instances:

If you are using IIS or apache check for the following parameters which affects the performance of php,

These are settings in

php.ini Settings:

session.gc_probability = 1
session.gc_divisor     = 100

session.gc_maxlifetime = 14400 - After 4 hours it resets all the Garbage collected Data.
