[mapserver-users] Mapserver search performance
Hello Everyone, I have programmed a GIS application using Mapserver, Google maps and Tilecache. The functionality of this GIS application is to extract the data (from the dbf file) for all features (Points) within a randomly drawn user shape and doing some statistical operation on that data. I use an NQUERY mode with MAPSHAPE attribute to get all the data for the user drawn shape. Mapserver takes aout 5-10 seconds for a small shape (a couple of square miles) but as the shape gets bigger (hundreds of square miles), the time taken to fetch all data related to the features/points lying in the shape grows exponentially (Upto 2 hours for some shapes). Until now, we were restricting the maximum area a shape can have but we have to get rid of that. Is there a way to improve the performance in any way? Will SHPTREE work for this purpose? The features are currently points only but we may move to polygons in future. We use the .shp files for the shapes. Is it advantageous to move to a database instead? If yes, what database works best? What I did notice is that for any given request to mapserver, however large the shape, the CPU utilization never crosses 12%. Can we improve performance by increasing the RAM or maybe move to a solid state hard drive? There is also the possibility of moving this application to Cloud computing. Anything that will improve the performance actually. Can someone point me in the right direction as to what might be the current bottleneck? T current setup is on windows and uses MS4W on an Apache server. Thanks, Varun ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

Hi, Shptree will help and stopwatch will tell you how much. Without spatial index Mapserver needs to go through the whole shapefile every time. Have a try, it will not take very many seconds to run shptree. Make different requests, take times with and without .qix files and you will some numbers. Change the requests and request order (query 1 with .qix/withour qix, query 2 without .qix/with .qix) so that you can see if you are actually testing the speed of disk access and memory cache access and not the effect of having spatial index. By adding DEBUG 5 for your layer you don't need stopwatch but you'll get timings into ms_errorfile. -Jukka Rahkonen- Varun saraf wrote: Hello Everyone, I have programmed a GIS application using Mapserver, Google maps and Tilecache.

Martin, fastcgi will essentially give you speedups in these two cases: * with slow-to-open data connections (i.e. oracle, some gdal/ogr datasources?) if you use CLOSE_CONNECTION=DEFER * and/or when the cost of creation of a process becomes non negligible compared to the time that the mapserv process will actually be running for each request. basically, there is little advantage of using fastcgi if your map draws are heavy, or if you are not using oracle connections.

[mapserver-users] RE: Problems with Query Template (Chameleon)
Not a Chameleon user so I may not be of much help. Any errors being logged? What does the template file look like? It’s possible that ms4w_2.3.1’s MapServer did not require a magic string be on the first line of the template. In new versions it is required. Basically the first line of a template must contain the string “MapServer Template”. Typically you’d put that in a HTML comment, e.g.: !—MapServer Tempate -- ...template follows... That’s my first guess anyway.

However when using the Query Widget (info of layers at mouse click) against MapInfo Layers it is no longer returning results, and yet it did previously. My knowledge is not that great in php etc – but I suspect that its requiring a dbf rather than MapInfo Tab as it does work with a shp, dbf set of files. Can Anyone help please as I really struggling – ideally I just want to use the old widget. However If someone can provide example of placing a button on a html page that would call query functionality that would be very helpful too.
