pdflrf command line DOS/Windows vs. Ubuntu speed comparison

Mobile Pentium 4, 2.8 Ghz, 512 Mb RAM

input files:
buba.djvu 1536 Kb
buba.pdf 13394 Kb (same book as buba.djvu - converted to pdf)

output DOS/Windows XP:
bubadjvu.lrf 8965 Kb - 285 seconds
bubapdf.lrf 9141 Kb - 590 seconds

output Ubuntu:
bubadjvu.lrf 8824 Kb - 208 seconds
bubapdf.lrf 16029 Kb - 950 seconds

Conclusions:
djvu to lrf - Ubuntu is faster
pdf to lrf - in both operating systems conversion is slower than djvu to lrf but DOS/Windows wins

My wild guess: the time critical step may be pdf to raster conversion; something is wrong with the pdflrf implementation in Ubuntu (warning messages - see my previous post).

The quality of all end results is perfect.
