Calibre on Ubuntu Toshiba problem.

sobi · 08-13-2013, 12:15 AM

I have an extremely old Windows PC (10 years old, I'd guess) and Calibre runs beautifully. I love Calibre. - I really do.

I also have a Toshiba NB205 with 2 megs Ram, and Calibre has always ran slow on it. I use Ubuntu on it, and keep both Ubuntu and Calibre current. This slowness has nothing to do with offloading, or reloading.

I have a 160 GB disk in the Toshiba.

I confess that I am no Ubuntu master, and have just sucked this up for 2-3 years, and will continue to do so. But it is really just about all I use this netbook for.

I also have an Astronomy program on it that runs like a little demon. So I don't think it is hardware. But I'm open to any advice.

Any suggestions must keep in mind that this is all I've really used Ubuntu for was this netbook, which has two jobs: Calibre and Stellarium.

So I'm no whiz kid. Feel free to talk slowly to me.

My Library is 10G, but it is a copy of the same library on the Windows machine.

Did you mean 2 GB of memory?

Well, yes.

@sobi, can you be a bit specific, which calibre features are slow - conversion, scrolling through book list, searching, downloading metadata.

Conversion can be cpu intensive, scrolling the booklist and searching can be disk IO intensive, and metadata down loads can be network bound on slow links or slow servers.

It could be that the disk is spinning down when its not used for a few minutes to save power, and the ATOM processor is not renowned for its speed, it was an Intel attempt to compete with ARM w.r.t. power consumption.

Conversion is slow, but that's not to much of an issue for me because I only convert where my nook demands it. Otherwise, I read what's there. What do I care?

Search is very slow. I don't usually d/l metadata on the toshiba. Anything where I would want to exclude from the list in a search is slow. So much so, I almost don't do it. My screen dims, nothing responds in Calibre.

If you search by entering an unqualified string in the search bar eg "Dickens", then try removing comments from Preferences->Searching->Columns that non-prefixed searches are limited to:

I had Calibre on an Acer netbook with Mint for a while, that made a big difference.

You might also want to try these settings

In Preferences->Miscellaneous set Max. simultaneous... jobs to 1
uncheck the Limit the max. simultaneous... setting
in Preferences->Behavior set Job Priority to Low

I know they seem counter-intuitive, but my perception is that Calibre runs faster overall with those settings, you can always reset them if they make no difference or worse
