Change amount of downloading/processing threads in ebook-convert?

khromov · 07-06-2012, 08:22 PM

Is it possible to configure the amount of running download/processing threads in ebook-convert? Checked the docs for ebook-convert and also the config files in ~/.config/calibre but could not find anything relevant.

I see at the start of a recipe.

Code:

1% Starting download [5 thread(s)]...

I am running this on a Raspberry Pi and the load spikes really high when running two recipes at once (i saw 5 min load averages of 17, then the device because unresponsive.)

I have found you can control this on a per recipe-basis by using the following line:

Code:

#override to 10 threads
simultaneous_downloads = 10

I also noticed some recipes has this jacked up really high, up to 20 threads (BBC News recipe).

Is there a global setting or a flag you can send to ebook-convert to override this behaviour?

No, there isn't. It is a per recipe setting.
