I notice whenever I compress something like a backup of my Thunderbird Inbox files (several hundred megs) in bzip2 format it goes nowhere near 100% or even 90% CPU usage. The problems I am talking about occur even when CPU usage is real low as well. :-\ >>The reason I wanted to see any changelog was to see if there is any >>changes to this part of the code at all before trying it, but file by >>file I would probably be lost since I am not a programmer. > > > The file is the most usual way to partition code. How else would you > know where to look? True. I meant I wouldn't know what files to look at since I don't know really anything about programming or how things are done internally. I'm kind of used to the subversion approach of revisions for everything instead of file by file. Then it would have one log showing all the changes of that revision all in one place. I see how the other way makes sense though. > Some other thing you might look at is if too many devices are sharing an > interrupt.
