Server performance when click button in accesspoint

[limingthefirst]

Hi,

I'd like to improve the performance of my QlikView application and Server hardware.

qvw file size is almost 8 GB, 256 G memory and 24 cores CPU

I can get some loading information with Devtools in Chrome, but can't get what happened in server when the browser is waiting for  the first byte of a response,such as hardware, CPU, memory and network? and how long they take?

Could anyone help me to post any docs or ideals with it?

Thanks.
