Why do Calibre uses RAM too much?
Just wondering.

Doing what? Converting, fetching news, the GUI with an empty library?
Conversion for instance will use as much RAM as necessary to complete the task in a timely manner. If you see huge spikes we can look into it to see if it's a bug or if there is a way to optimize in that instance. |

No. I am doing nothing. I just let it open and it consumes too much.
Have a look: |

Thanks for the reply. I guess I may have to rephrase the question.
Why do Calibre uses a large amount of RAM (even if it is not doing any job)? |

If you want calibre to have less worker processes: Preferences, Miscellaneous and change the number of worker process number. |

Try comparing Calibre's memory footprint with some commonly used programs. It's not that huge, if you get down to it.

Don't look at any program's used amount of RAM unless your system slow down/hang and you need to discover the problem. Sometimes Firefox uses over 500 MB but my PC still performs smoothly (with calibre and Photoshop running).

It's at 87,548 now. I don't usually worry, since windows will use whatever it can, and adjust as needed. It is interesting that it climbs though, without even opening the window. It's now at 87,632. Is that a leak? |

Mine does not change unless I do something with Calibre.
Why would I have Calibre running if I was not going to use it? |

Seriously, I usually don't open it unless I need to do something, but then I leave it running until I go to bed, since I use it on and off through the day. Today, I kept it minimized and watched the numbers just to see what happened. FTR, after testing it, I thought it might mean I had a problem with Library 1, because it climbed 4 kbs every 3-5 secs, but stopped climbing when I switched to library2. But it stayed stable even when I switched back to library 1, and after trying a few restarts, it looks like it doesn't matter which library I start on, it climbs 4kbs every few secs, until I switch to another library. Anyway, that's my data for whomever wants to know. I usually don't look at resources like this, because it'll make ya crazy. I can say for sure that, when things do seem draggy on me, it's usually because of Firefox rather than calibre, even after I've been working it hard. |

As long as everything works I could care less how much memory it's using. |

Firefox is the beast, at least if you're using some of the heavy addons or load certain sites. It's worth it, though. |
