It seems as the Gimp takes longer for the conversion ...

the slowdown is mainly because i have to load and save the file for each
single conversion ... imageMagick does that conversion in one wash up ...

It's because I can't put single script-lines together and run the script
because the plugins just get read when gimp starts up (and i have it running
all the time)


Here are the times you wanted ... all times are taken with the files in memory
(with the gimp I can't say it really as it is estimated by an php-script)

convert was called manually from the commandline
