I can see in my task manager that ESS is using around 30 to 34 mb of RAM and while scanning it uses around 40 to 50 mb and 15% to 45% of cpu. when i was testing KIS 7 on same computer it was using 10 to 30 mb RAM normally and 40 to 50 mb RAM and 40% to 65% usage of cpu while scanning. Now my question is, it was clear to me that system was bit slow when kaspersky was installed and i felt system drag. BUT there is no question of system drag or slowness while using ESS. So can anyone tell me why is it so?
