Re: [mapguide-users] alias - unc - performance issue
Another thing you could try is to enable connection pooling for the SDF provider in serverconfig.ini (pooling for this provider is disabled by default) - Jackie -- View this message in context: http://osgeo-org.1560.x6.nabble.com/alias-unc-performance-issue-tp5219621p5219960.html Sent from the MapGuide Users mailing list archive at Nabble.com. ___ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users
Re: [mapguide-users] alias - unc - performance issue
I can confirm that UNC paths work ok. I haven't run any performance tests, but haven't really thought to run any because it doesn't seem to be a significant problem for my users (using MGOS 2.5). Inherently, I think performance could be better if the data is on the application server, but on the practical side, if you are using the data for other purposes and needing to manage/update the data, using a shared network drive is a practical solution. There is an old wiki (about 4 years old now) that I posted Configuring Aliases https://trac.osgeo.org/mapguide/wiki/ConfiguringAliases suggesting that you could not configure an alias using a mapped drive. That needs to be amended because you can configure an alias using a mapped drive as long as your application server has access to that mapped drive. In my current MGOS setup, I have both UNC and mapped drives configured as aliases. Hope this helps. -Steve -- View this message in context: http://osgeo-org.1560.x6.nabble.com/alias-unc-performance-issue-tp5219621p5219815.html Sent from the MapGuide Users mailing list archive at Nabble.com. ___ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users
Re: [mapguide-users] alias - unc - performance issue
Do you use actual UNC syntax? (\\servername\share) Or is this mapped to a drive letter? I've observed in general (not just MapGuide) that access to files on UNC shares are generally faster when mapped to a drive letter than through raw \\servername\share syntax. - Jackie -- View this message in context: http://osgeo-org.1560.x6.nabble.com/alias-unc-performance-issue-tp5219621p5219630.html Sent from the MapGuide Users mailing list archive at Nabble.com. ___ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users
Re: [mapguide-users] alias - unc - performance issue
Hi Jackie, I use UNC pathes, not a mapped drive. I tried a mapped drive as well - I can create an alias for a mapped driave via web-admin interface but it is not shown in Studio/Maestro. I read in a few postings that mapped drive do not work - at least it doesn't work for me.

[mapguide-users] alias - unc - performance issue
Hi So far we have put all data on a local drive (VM W2008R2). We would like to move data to a shared drive ( 30GB of data to be shared between three MapGuide servers for readonly access). I did a test and created an alias using an UNC path pointing to a shared network folder. Same map, same SDF file, same layers, same scale and extent - the difference is enormous - consistently (tested on two different servers): Performance report : # sdf on local drive Total Generation Time: 664.23 ms Layers: 409.67 ms (61.7%) # sdf on network drive via unc/alias Total Generation Time: 8,683.02 ms 8,399.52 ms (96.7%) (Layers) I cannot rule out a slow network drive completely but it is unlikely (according to our IT): - UNC shared drive - we have this setup with MG 6.5. and it works very well - All data (VMwares, shared drives) use the same storage system Looking through the MGOS mailing list archive I see that perfomance and aliases were an issue in the early days of MapGuide (around 2007/2008) - but nothing recent. So, I'm curoius - has anyone else made negative experiences using an alias and shared drives? Is there something I can do with regards to configuration / testing? Any hints or suggestions? We are currently using MG 2.4, an update is not an option right now (due to dependencies).
