Hi Dave,
Sorry for being vague in the first place. I am still a rookie to the Mapguide Open Source world.
Please find the response below for your questions.
What configuration are you using? .NET, APACHE etc..
We are using .NET with IIS7 on Windows 2008 Server 64 bit
Are you using Basic or Flexible Web Layouts? What kind of data/providers are you using?
We are using Basic Layout embedded in an aspx page. We are using DWF and SDF files for the graphics with many of the SDF joined via the ODBC provider for dynamic access to tables in the database as the database is updated regularly. There is 1 SDF layer, 4 DWF layers, 13 themed SDF/ODBC joined layers, and 8 labeled SDF/ODBC point layers. The map xml is generated dynamically based on a user picked value from an aspx page.
Are you using raster imagery and if so what format?
No raster
Yes the 64 connection limit has been removed, but other components including the Berkeley database and physical disk I/O for example will limit the number of concurrent connections?
We have followed the criteria for optimized settings based on the webconfig/serverconfig document that Trevor published.
What is your hardware? How many CPUs/cores? Is everything running on the same box?
Two Virtual machines load balanced using F5 Load Balancer running MG and the .net code. Both machines have Intel Xeon CPU 2.6ghz 2 processor with 4 GB of RAM. SQL Server 2008 runs on a separate machine and currently the SDF files are stored on a separate machine although this was done recently to try and reduce disk IO on the server.
What are your users doing at the time things lock up?
We start at the initial screen and pick a value to load the map. Two or perhaps three may get the map loaded, all others will sit and wait until the server ultimately fails.
Hope this will give you some information on what we did.
I appreciate your help on this.
Thanks,
Bala

You will need to provide a lot more detail than "it doesn't work" to get a useful response :)

Hi,
We just started testing 64 bit MGO 2.2 on windows 2008R2. When we load tested our site with 10 simultaneous users, the Mapguide service stops responding and we had to restart the service.
I thought MGO2.2 is fixed to handle around 500 connections at the same time compared to 64 connections in MGO2.1.
Please throw some ideas for the performance issue.
Thanks,
Bala
