Is it just me? or...

I've been using Calibre for some time and have so far, found it extremely useful and user friendly. Until, that is I updated it to rev 0.7.2. At that instant, it changed from being all of the above to something that gobbled up machine resource and slowed the machine down to a snails pace. I'm running Calibre in Mandriva Linux ver 2010.0, on a machine with plenty of resource. On opening Calibre, the system monitor showed that memory allocation rose to encompass the entire amount of RAM (4 GB) and then went on to fill the SWAP to 4GB, without even filling the screen display, which took several minutes to complete. During this time, the system monitor showed that one core of the four core Athlon CPU was running continuously at 100%. When the screen became available, the CPU usage went down.Selecting a file sent it back up again for about five minutes. Selecting edit meta date, another five minutes. All this time, to the accompaniment of grumbles from the HDD the SWAP space was slowly filling up. It reached 5GB before I lost patience.
Is there any way of going back to the revision of Calibre before this one?. I'd hate to stop using it, but at the present it's just unuseable.

I seem to have solved the problem (sort of). I noticed a reference to older versions on Sourceforge, so, I downloaded version 0.6.55, unpacked it and replaced the current, problematic, version with this, and, lo, I have Calibre back again as fast and resource lean as anyone could desire. . My only desire now is to move the database onto my server, where it's accessible from any of my machines, and not just this one. Anyone know how? Without wrecking the thing, that is.

Your experience is anomolous. I find that the latest releases are significantly faster than any of the 0.6.x series, and no more RAM hungry.

if nothing is done to track down the cause of your issues then you will be stuck on that older release and thus be unable to enjoy all the new functionality recently added to Calibre which I have found makes it much more useful and enjoyable to use.

Must admit, Rod, that I was so happy with the first version of Calibre I downloaded over a year ago that I've resisted all temptation to upgrade. Couldn't be happier with my 'old' software. Likewise, I've never installed new firmware on my reader. I'm a great believer in not fixing something 'less it's broke. Cheers. Neil

There's definitely a trade-off between "it does what I want it to do - so why risk an upgrade" and "if only I'd known about all those wonderful things I was missing I'd have upgraded long ago."

In this case, I agree with itimpi. Calibre is changing so fast that upgrading regularly is worthwhile. For a more mature program, I lean towards leave it alone and don't upgrade, but for an actively developed program I'd upgrade. Even if you have one of the minor problems specific to your setup/e-reader, it will get fixed quickly if you report it.

Most of the upgrades I've seen since I first got calibre weren't of any interest to me (this is not to denigrate them). 0.7.0 (or was it 0.7.1?), however, was a huge improvement, especially the customizeable columns. I keep my previous installation files (so I can go back if I want or need to) and check out each new upgrade I install as throughly as possible before committing too much to the new upgrade. If the new upgrade buggers up my library so it won't work with an earlier version, I can always download the versioned copy I have on line with Carbonite.

Running Calibre under linux, I haven't thrown away the problematic release. I simply renamed it in /opt, the install directory and copied alongside it an unpacked copy of an earlier release from sourceforge. With the next upgrade, I'll do the same thing, then if there are problems I simply rename and carry on with the earlier release. A whole lot simpler than using the linux update script. There are advantages, after all, of having once been sysadmin on a Unix system!
