ecw files

[Kevin Flanders]

I am using ecw files (and sid files) on a few projects, and am wondering...

1.  does mapserver have to decompress these files to use them?
2.  if so, are files compressed at 20:1 ratios faster than files compressed
at 100:1 ?

3.  Does anyone have info on the performance of sid files compared to ecw
files?
