#2033: Moving g.pnmcomp to lib/display to improve render performance of wxGUI
----------------------------------------------+-----------------------------
Reporter: huhabla | Owner: grass-dev@…
Type: enhancement | Status: new
Priority: major | Milestone: 7.0.0
Component: wxGUI | Version: svn-trunk
Keywords: display, Python, multiprocessing | Platform: All
Cpu: All |
----------------------------------------------+-----------------------------
Comment(by huhabla):
I have updated the display benchmark script to compare the PPM performance
of PIL and g.pnmcomp. System: Ubuntu 12.04 LTS, AMD Phenom(tm) II X6
1090T Processor, 16GB RAM, 1TB Harddisk. Please make sure that you have
the latest grass7 svn version to reproduce the benchmark results, since
there was a bug in the pygrass Module run() function, that did not allow
parallel process runs.
