High Response after system restart

Hi All,

I've performed fine tuning in ST02 and currently I have zero swaps or paging in ST02 which seems to be fine.

But whenever I restart the system, it takes long time to load any transaction for the first time which for sure seems to be the time

taken for the request to load to the buffers.

Even opening the initial login screen for the first time takes more than 30secs but later it will come in 1 sec which is the same with the transactions also.

Could you kindly help me to reduce this response time by giving valuable inputs.

Thanks and regards,

Nikhil
