[mapguide-users] Hardware requirements to support multiple users?

[Chris White]

I'm experiencing similar problems with cpu usage and general speed of
performing simple tasks such as panning around a map. The test server
I'm using is Pentium 4 HT 3ghz with 1gig of RAM running Windows Server
2003 and serving MapGuide (in the Windows IIS configuration) being the
only service running on it. I currently have about 300mb of data in SDF
format (imported from SHP) and the problem is seen even when zoomed in
on the map. 

 

Are there any know performance issues or optimisations to the data that
I can perform to improve this?

 

Thanks 

 

Chris

We're developing a product that utilizes GIS data for a spatial
selection source and are considering implementing the GIS solution
utilizing MapGuide.

 

On a common day, there would be 140+ users continuously loading map
data, creating a point, line or polygon, and saving the data and exiting
the application.

 

>From my local testing, it appears that MapGuide is a CPU intensive
program and I'm wondering if it would support this type of environment.

 

Some sites would require access to the map data source via an ArcSDE
FDO. In my testing with the ArcSDE FDO in MapGuide Studio , I've
observed some real speed of loading data issues along with several tiles
not being displayed when using the Ajax viewer in a .net application
with Windows 2003 server environment. Other sites would be using
shapefiles as their map data source. Again, the same issue was observed
with some of the tiles not being displayed.

 

With only one person (Me) utilizing the Ajax viewer a simple request or
pan operation on the map tends to spike the cpu usage to the ceiling on
my test server. I'm not sure if it would support the number of users we
would require in a production environment. I've tested using both the
.fcgi and MapAgent.exe as the web service extension configuration. As
some of the other threads mention, I did see an increase of reliability
with the mgserver.exe service not dropping when deployed with
MapAgent.exe defined as the web service extension vice the .fcgi

 

Do any of you have any recommendations on hardware required to support
this type of environment using MapGuide? 

 

My test server has Twin 3.0 GHz Pentium processors with 4 gig of RAM
with VMWare virtualization software running multiple OS's to create a
development testing environment. I know that this is not an optimal
testing environment to get a good idea of performance.

 

Each OS has 512 meg of RAM reserved for it's use. The MapGuide server is
the only OS that has a CPU intensive application running.

 

 

Thanks,

 

Dave
