EP Performance Tunning and concurrent user login problems

Hi all.

We have a EP , integrated with Windows AD and SAP R3.

In real situation, there will be 1000 users login in EP in 0.5 hours. And their operation time will be 6-8 hours, connect to R3 or other applications.

Is EP can support such concurrent user login scenario ?

if EP fails, is there some performance monitor tool or performance tunning issue ?
