Re: [Opengrads-devel] Dat File re-reads

[Brian D. <do...@co...>]

Ok, not too hard, I've added some basic caching of the map file to  
gxwmap.c.  The changes are all isolated to gxwmap.c for now.  I kinda  
did this quick so I haven't done a whole lot of testing on it.  The  
cache lasts for the entire grads session.  I don't think this hurts  
performance any for those cases when grads is just being run to do one  
plot.  This mod is applied to the gxwmap.c from the 2.0.0 code base --  
but we will not include it in 2.0; it will be included in 2.1.  Right  
now the CACHEMAX is set to 2MB which will cache lowres, mres, and  
hires.  If you have your own map files that are larger, you may want  
to increase the CACHEMAX value.  This will have no affect on shapefile  
usage.

Gary, I'm not really sure this will help your situation; it will  
depend on your system environment.  Arlindo's suggestion to set up  
some system-wide solution like a ramdisk may be more along the lines  
of what you need... Brian
