[vwnc] FW: help on performance test for SmallTalk+GemStone/S application

Hi there,

I have been trying to run a performance test for a client-server application based on SmallTalk+GemStone/S, however so far, we have NOT been able to get LoadRunner tool working for such environment.

Wondering if you can kindly provide any advices on how to do performance test for such applications?

thanks a lot.

Joshua

Hi Joshua,

I'm not familiar with the LoadRunner tool you mentioned. I know that
there is a tool called LoadRunner built by HP which does, or claims to
do, end-to-end performance testing, but I don't know if an interface
has been built that supports VisualWorks Smalltalk.

If your client application is written in VisualWorks, client
performance can be measured using a number of profiling tools that you
can load from the Parcel Manager. Load the All Advanced Tools parcel
and this will add a number of menu option to your Launcher's Tools
menu. From there you can do various Time & Allocation profiling using
sampling.

As for getting profiling information for GemStone/S, there are a lot of
things to look at. If you want to know about the GemStone VM
performance, you can look at the GemStone class ProfMonitor. If you are
looking to understand database performance, you can look at some of the
VSD statistics which are available. This is a very big area of study
and GemStone even offers some classes geared toward understanding how
to tune your GemStone system. If you want to know more about GemStone
performance, I might suggest you post your question on the GemStone
mailing list. There are a lot of people there who have a lot of
experience tuning GemStone applications that can help you.
