Enterprise Manager is very old now and loading a huge number of runs into it will be pushing its performance to the limit. You mentioned 2000 VSOFs, but is that one test per VSOF (should be OK) or many tests per VSOF? In fact the VSOF is only part of the picture, the size of the coverage model (*.ucm) files is also significant.
You can run the tool in 64-bit mode using the -64 option to emanager; this might gain you some performance as well, because the garbage collection will be less frequent.
What I would really recommend though is for you to consider switching to the new vManager Client-Server technology, as this is our new tool. It's going to replace emanager and has a much more capable GUI and can handle vastly more tests and coverage data. There is some change to the use model so I think you should talk to your local Cadence Applications Engineer for guidance. If you don't know who your AE is, send me aprivate message indicating your contact details and which company you work for and I'll put you in touch with the local AE.

Hi Steve ,
Question 1: For the vManager Client-Server technology, which one should be download from Would it need a new license ? If yes, I won't install it.
Question 2: Currently, I dont want to change tools. Even I use the option -64, it is very slow. How could I make it fast ? It seems that my memory configuration is not very good. Could give me some help to improve it ? All my coverage file data is only 136M. Why should it consume such big mem and such a long time? I am confused.
In reply to JennyYang:
Jenny, the new technology is already a part of the Incisive isntallation, but only from Incisive 13.2. Yes, it takes a different licence, but because we will be phasing out emanager, at some stage you'd need to consider updating anyway.
As for the performance of emanager, you should open a support case at http://support.cadence.com/ so that one of our engineering team can take a look at the specifics of your case; it's not really possible to help you based on the very limited information that you've posted here, and we may need to see the coverage model to diagnose the issue.
The size of the UCD (data) files is not important, what really matters is the size of the coverage model (UCM file). If you have a lot of code coverage enabled this could be part of the issue.
I had updated to INCISIV13.2 (14.1 software download from your web has problem with installation.)
But the 13.2 emanager performance does NOT improve .It tooks more than 10 hours to collect the 2000 vsof+ucd files (There are UCM files, each UCM file is about 550k byte)
Do you have any suggestion for me to generate/collect the functioin coverage for several thousand test.
