Re: [mapserver-users] MapServer performance question - slow on different machine
the only difference seems to be the presence of MapCache on the slower system. Could you try removing it ? hth, Umberto On Thursday, July 25, 2013, andy wrote: On 7/25/2013 1:56 PM, andy wrote: On 7/24/2013 10:59 AM, Mark Volz wrote: Hello, ·The machine is using a 6.8 out of the available 8GB of RAM oI think we need more RAM on the system, however I am curious as to why the MapServer 5 application ran fast, while MapServer 6 is slow.

[mapserver-users] MapServer performance question - slow on different machine
Hello, I had an old MapServer application running on a production machine. It used IIS and it ran fast. I upgraded the application on a development machine. I switched over to Apache (for MapCache) and the new application ran fast on my development machine. We moved the new application onto the production machine. It does not run fast. I am trying to figure out why MapServer 5 would run fast under IIS, while MapServer 6 under Apache runs slow. There are a couple possibilities, if anyone could confirm the following as a problem, or has a solution please let me know * The machine is now running both IIS on port 80, and Apache on port 8080. o I have a similar setup on another server, and this does not seem to be a problem at all. * The machine is using a 6.8 out of the available 8GB of RAM o I think we need more RAM on the system, however I am curious as to why the MapServer 5 application ran fast, while MapServer 6 is slow. Could IIS just behave better than Apache under low RAM situations? o That being said both Apache and MapServer take a minimal amount of RAM Machine Specs: Developer Machine * MapServer 6.1 MS4W 3 Beta running Apache with MapCache * 4 Core, 16 GB RAM Production Machine * MapServer 6.1 MS4W 3 Beta running Apache with MapCache on port 8080 * IIS is also on the machine on port 80 * 8 Core, 8 GB RAM * At one time IIS was running MapServer 5 at a reasonable speed Thanks for any help or ideas Mark Volz, GISP GIS Specialist ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
