Merge Replication Performance Tuning and Optimization

Hi Guys,
I have been analysing our merge replication for the past 2 months with
ongoing performance issues. I have been in constant talks with Microsoft
regarding performance and bug issues within merge replication and have had
numerous fixes and hot fixes set to me.
We have found multiple issues within nested views and revaluation of data.
So the time has come to revaluate some of our database design to resolve
some potential issues.
MS Support sent me this article
(http://www.microsoft.com/technet/pro...n/mergperf.msp
x) relating to performance tuning and optimization and I would have to say
what a superb document it is. However I would like to rebuild our test bed
with automated publisher and subscriber changes to verify bottle neck and
performance. The original people that wrote the where Damian Castro,
Alejandro Miguel, Bren Newman.
What I'm looking for is some automated database scripts for hitting the
publisher server with more that 200 users over a period of time as
subscribers. Does anyone have any idea where I could get theses scripts that
these guys used or would I have to start writing them now.
Any help would be greatly appreciated.
Thanks, Tim.
Capture representative load using profiler. Then modify these statements to
simulate 200 users. Make sure you don't run the script in a batch as this
will not simulate a representative load. You will have to stagger the
statements to reflect the order and frequency they are run in.
Then fire up osql in 200 different sessions to run these scripts.
Note that with merge replication you probably will want to minimize the
number of concurrent sessions.
