Hi all,
I have developed an app that draws OSM maps like so:
NSImageView subclass:
==========================
- (void)drawRect:(NSRect)rect
{
[[NSColor whiteColor] set];
NSRectFill(rect);
NSBezierPath *path = [mapPath bezierPath];
...
[path fill];
...
NSBezierPath *path = [mapPath bezierPath];
...
[path stroke];
...
}
On my development machine
System Configuration: SUN MICROSYSTEMS SUN FIRE X4170 SERVER
Intel(R) Xeon(R) CPU E5540 @ 2.53GHz CPU 1
Intel(R) Xeon(R) CPU E5540 @ 2.53GHz CPU 2
drawing the map/image (execution of the drawRect: code) is ultra fast (no delay
at all).
However, on the production system
System Configuration: Sun Microsystems Sun Fire X4240 (2.7GHz)
Quad-Core AMD Opteron(tm) Processor 2384 CPU 1
Quad-Core AMD Opteron(tm) Processor 2384 CPU 2
drawing the image (execution of the drawRect: code) takes 3-4s! :-( I do not
want to believe that the Xenon CPU is so much faster and rather suppose a
difference in the set of installed (used) libraries!? I use
rsync -avz -e ssh /opt/GNUstep root@<target machine>:/opt
to deploy my software. So at least everything below /opt/GNUstep must be
identical!?
I am clueless!! What can I do to find out which non-GNUstep libs responsible
for drawling are used and why drawing takes so long on the target machine? Any
ideas?
Thanks a lot in advance,
Andreas
BTW: My GNUstep tree is a couple of years old:
cd back
./configure
make
make install
