Re: [UMN_MAPSERVER-USERS] FW: [UMN_MAPSERVER-USERS] Performance Difference between 3.6. and 4.6

Title: Message

Are there any visual differences in your map output? The reason I ask is perhaps labels in 4.6 are being drawn with not vector fonts. Otherwise I don't see any reasons why 4.6 would be slower. 256MB of RAM is pretty tiny prehaps the SuSe distro is tieing up more system resources causing significant swapping.

Hi,

 

Here's the -v. I recompiled v 4.6.1 with fewer options, but to no noticable difference. I can post its latest incarnation tomorrow.

It might be helpful to post the outputs of

 

mapserv -v

 

for 3.6 and 4.6

Hi,

 

This is a repost from a couple of weeks ago. I could still do with some advice/info so rephrasing.

 

Can anyone tell me if I should expect a decrease in speed of image rendering moving from version 3.6 to 4.6? Currently when displaying tileindexed layer of approximately 200 shapefiles I get a big performance hit. With 3.6 images are drawn in 2s or less, with 4.6 its 4s or more depending on the number of arcs being displayed. Both datasets have been shptree'd and sortshp'd using their associated executables. There are hardware differences, they both have 256Mb RAM otherwise the 4.6 machine has a faster CPU and HD. 3.6 machine is running on RH Linux 7 Apache 1.3. 4.6 machine is running Suse 9.1, Apache2

 

Should I expect any performance differences between Apache 1.3 and 2?

I've tried compiling 3.6.1 to run on the same machine as 4.6 version, but I'm getting an "undefined reference to `__gxx_personality_v0'" error message on make. Looks to be something to do with gcc and g++, but I haven't been able to find a solution. I'm not convinced I'm on the right path, so any advice the list can give is appreciated.
