Hi Kaushik,
as I said - there are so many factors influencing the speed.
You didn't give any numbers regarding hardware the system is running on:
Type, speed, number of CPU's
Memory settings
Disk settings
DB settings
And so on. Which sizing guide did you follow?
Which version of WCEM with PL, J2EE and so on do you have?
What do you mean with "trace level 1"? Is this Errors only or debug info? How much lines of trace do you get per time?
You have a license for WCEM, hence you might be entitled for support - please check. Even if it is a sandbox system we can have a look at it if you provide WTS access.
Please file a OSS ticket or provide more comprehensive information, I don't see any chance to help you here without it.
BTW: What do you mean with "Initial load"? Of what: WCB? Application? Just the first call of the application after server restart is slow? This is quite normal as there are lots of one time initializations, but the following calls should be much faster.
Kind regards,
Patrick
