I just couldn't leave this one alone. The cataloged_times is just a dictionary so there is no real need to use pickle to serialise it. I loaded the file into python and created a serialise file using msgpack instead. This reduced the file size from 3.1MB to 1.7MB. I then changed software center to load this file instead of the pickle one bingo! this reduced the load time by 1.1 seconds to just 0.1 of a second.
Only thing is the change would also need to be made to the upstream apt- xapian-index code that actually creates/updates this file, I'm unsure at this point where this code is located. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/845579 Title: software-center terribly slow, ubuntu freezing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/845579/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
