BibleTime using a lot of CPU processing power
Hello everyone,

I am new to using BibleTime, and this is my first post on the Crosswire forums. With that I am not sure if I am posting in the correct area of the forums, but I do use BibleTime with my desktop, so I will post here.

I use Ubuntu 9.10- 32 bit, on a Quad Core 2.4mhz, Intel machine with integrated graphics using 4 gig of RAM. I notice that BibleTime uses a lot of CPU processor power. One of my CPU's is always using 100% of its' capabilities and the others remain under 5%. This is a lot when other applications usually use a combined CPU usage of less than 5%. A good example of this is the application Xiphos Bible Guide, I can read Bible text, and have an auditory synthesizer speak the text all for less than 5% CPU usage. I don't use many of the features in Bibletime, all that I really want, is to read bible text.

My question is this: Are there processes/features that I can turn off to reduce the CPU load on my machine?

Thank you.

Mike

    Mike,

    Thanks for your report. I am trying to reproduce this on a ubuntu 9.04 quad core system. I can't do anything that gets the continuous cpu usage above a couple of %.

    You did not mention the version of BibleTime. I think the one that comes with ubuntu is an older version. You could try updating to a later version. Use the crosswire ppa repository where there are newer versions of bibletime, currently 2.5. See http://devel.bibletime.info/wiki/Packaging#Ubuntu_Linux for installation instructions.

    Hello Gary,

    I am having a little trouble with the Sourceforge site. I think it be my Firefox browser settings for security. I have tried to send you a screenshot of Synaptic Package manager in Ubuntu 9.10, showing the Properties of the version of BibleTime installed on my computer. I don't know if the Screenshot was uploaded or not.

    Here is an outline of the properties, which are, I believe, the most recent version of BibleTime.
    Installed Version: 2.5-1~Karmic1

    Lasted Version: 2.5-1~Karnic1

    Edit: I have the Launchpad PPA for Crosswire Packaging Team installed in my software sources. Would this ensure that the newest version of BibleTime would be made available to me??

    I have the PPA for Crosswire installed. Also I use Ubuntu 9.10 as an OS, not 9.04, if that would make any difference.

    Hello Gary,

    I have been thinking about your efforts at providing BibleTime to users. I am still quite new to Linux and computers in general. If, you think I could be helpful in testing BibleTime in a VirtualBox vm, or with another hard-drive install on an adequate unallocated space on my Hard Drive, I might be consider doing this. My present plan is to remain with Ubuntu 9.10, until ~Oct 01, 2010, before doing a fresh install of Ubuntu 10.4, and bringing my /home folder from its' own partition, forward at that time.

    Or I suppose, If you would prefer testing of BibleTime on Ubuntu 10.4; I could probably do this too, but I would wait until the frozen period before its' release is finished and the Official version is out.

    Just some thoughts,

    Mike

    Mike,

    Testers are always welcome. You can find some suggestions about testing at http://devel.bibletime.info/wiki/Testing_BibleTime. You can also find information about our mail list and IRC channel at http://devel.bibletime.info/wiki/Main_Page.

    I have a laptop with several partitions on the disk. I can multi-boot to Ubuntu 9.04, 9.10, 10.04beta2, Fedora 12, and Windows XP. I have tested your cpu usage issue on all of the linux systems with the latest BibleTime code. I also tested BT 2.5.1 on Ubuntu 9.10. I still don't see your problem.

    BibleTime 2.5.1 is the latest packaged version for Ubuntu. We have the source for the 2.6 version on SourceForge.

    Gary

    Well, all I can think of is that I use the gnome-desktop and that BibleTime depends on the KDE environment with QT, and that causes the heavy CPU use on my computer. Any new suggestions will be appreciated.

    I have again tested this with ubuntu 10.10 and the latest BibleTime. I am also using a 4 core computer. If BibleTime is just sitting with no mouse movement the cpu usage goes to zero. If I actively move the mouse over a KJV bible with strongs numbers, I can get the usage up to about 5%.

    I am closing this.
