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.
	 
	Steve
