I did a VERY unscientific test, rendering a 200 x 200 and a 300 x 300
points shape file in trunk, renderer branch and composer_redesign
branch. The points were autogenerated from a C-program to a delimited
text file and then saved as shape file. All branches were compiled with
debugging off.
Using circles with size around 20, in renderer branch larger.
Result:
branch layer sec
----------------------------
trunk 200x200 4
trunk 300x300 8
render 200x200 7
render 300x300 13
composer 200x200 16
composer 300x300 32
The delimited text files (gzipped) for those interested are stored at
links below. It would be good if anyone could confirm the discrepancies.
