Hi,

I have installed Calibre on a server without GUI, therefore I only use Calibre from command-line.

My server has 4 CPU cores, but Calibre only uses 1 for a conversion job. I would like it to use all 4 when I start a conversion.

I have tried to look into global.py and tweaks.py, but I cannot find any parametre for forcing all CPU cores.

Does anybody know if it is possible for Calibre to use all CPU cores? And tell me where I can find configuration for this?

I have another machine with GUI Calibre installed, and from this interface I have found a setting: max simultaneous conversion jobs (Preference ->Misc)
Does this setting do what I desire? And If yes, how can I change this setting from command-line?

Grateful for all replies!
