I was faced with a sad situation. old server has i7 3770 (3.4 Ghz up 3,9 GHz) CPU with 16 Gb ram. New one server has one E5 2690 v3 (2,6 Ghz up to 3,5 Ghz) CPU with 128 Gb ram
Here is compatible list from intel ARK | Сравнение продукции Intel®
on both servers installed Windows 2008 r2 server and QlikView 12 SR1
visualization rendering, objects in the container is faster than on the old server to the new one.
new server is slower by about 60%. For example on the old server object mapping occurs for 3 seconds. The new server is the same action takes 5 seconds. Applications are identical.
At this point, the load on both servers is minimal. And do not show any peak CPU load
really visualize rendering is calculated on a single core, and highly dependent on the maximum clock frequency of one core
