[winGRASS] some really slooooowwww functions

[Matt & Kim]

Hi All,

This is my first post to wingrass, though I've been a lurker on 
the main grass channel for a year so and have opened my mouth
there once or twice. I'm a GIS professional (ArcInfo, plus a
smattering of others) and am trying to get seriously acquainted
with grass. My coding ability in anything other than Arc Macro 
Language or dos/nt cmd files is pretty close to nil, sorry. 
Cheers. 

I'm sure I'll have more questions later, but at the moment there
are only 2. I have no idea if they are related.

1) When running many grass commands  instead of the expected
output I get:
	grass5.0.0pre2_i686-pc-cygwin_bin.tar.gz: No such file or directory

for example:
	GRASS:/usr/local > g.setproj
	WARNING!  A projection file '/home/obelix1/g-data/yk/PERMANENT/PROJ_INFO'
	[...snip...]
	Please specify projection name
	Enter 'list' for the list of available projections
	Hit RETURN to cancel request
	>list
	grass5.0.0pre2_i686-pc-cygwin_bin.tar.gz: No such file or directory

For the above session a text file containing the expected 
output can be found in 
D:\cygwin\home\Obelix1\g-data\yk\landsat7\.tmp\OBELIX\1396.0

In an attempt to remedy the situation I uninstalled grass5pre2
(using the uninstall script) and installed grass5pre3 by simply
unpacking the archive into /usr/local/grass5 and symlinking
the grass5 startup script to /usr/local/bin/grass5.

The error message remains the same. Note the 'pre2' in the 
filename. The pre2 archive no longer exists anywhere on my 
harddrive.

2) I've been trying to bring in some GeoTiff imagery and it is 
taking an incredibly long time, over 12 hours for a single 17.6mb 
image using r.in.tiff. This can't be normal (right? please?)

Task manager reported ~150mb of ram being used and 99%
CPU utilization (figures from memory and before I upgraded
to pre3).

Right now I am using r.in.tiff on a 4.4mb geotiff. At about 
the 12 minute mark Task Manager reports:

	r.in.tiff
	cpu%	: 99 (range is 85-99)
	cpu time	: 09:00
	memory	: 69,040 K (going up, very slowly)

	processes	: 42
	memory usage	: 374,094 K / 1,277,936 K

The cdrom drive where the source image lies spins up every 5 
minutes or so. (In previous tests the same slowness is observed
on images on the harddrive and within the cygwin directory
tree).
