KEEPING SEVERAL APERTURE LIBRARIES
I am using Aperture as both my digital asset management system as well as for doing post processing. That is I do not do very much in in Aperture besides some minor fixes to the picture. For major things I mainly use the Nik Software (http://www.niksoftware.com) suit for most of the things I do in post. All of my pics have been in one Aperture library which means that the total number of pics in this library are getting close to 50.000. The library is stored on a Drobo (http://www.drobo.com), a device that can hold 4 hard drives and which also set up the hard drives in a sort of RAID system. This means that if one hard drive goes down I can just pull it out from the Drobo and replace it with another drive without affecting my big Aperture library. However, I have the latest months noticed that Aperture has become extremely slow. Start up time of appr. 10 min, moving a picture within the library/project took ages - in other words I saw the spinning beach ball very much more than I wanted to. I suspected that it was the Drobo, but now it seems as if the problem actually is Aperture. It seems as when an Aperture library goes above 10.000 pics it starts to slow down. Listen to this Audioboo by Scott Borne -http://audioboo.fm/boos/66432-lightroom-aperture-tip. So I have now started to divide my Aperture library in to smaller ones. And I have done it as per this advise -http://www.johnthawley.com/journal/2009/5/11/managing-multiple-libraries-in-aperture.html. It took some days to create the new libraries and move the pics in to them, but I hope that I now will have a much more faster and efficient work flow when using Aperture.
