Hi,

i could be that IM is compiled with 16bit support whereas you only need 8bit support (should be far enough for web images).
launch "identify -version" in you shell, if you see Q16 somewhere at the end of the line it means IM is compiled with 16 bit support.
Then you have two options : 
- recompile IM with 8 bit support with the following flag : --with-quantum-depth=8
- force 8 bit support at runtime with the following command line parameter : -depth 8 (this can be done with the "params" parameter of the imgResource Typoscript object).

You could also try GraphicsMagick which might be faster in your case.

As a matter of fact it has always been quite slow for my other deployments, but 60 seconds on a new server is pretty surprising.
