[Shotwell] Use ionice?

[shuihuzhuan at free.fr]

Hi,

I definitly switched to shotwell 1 month ago. It works quite good and I'm very happy. 

However one thing is really annoying : the big filesystem scan at launch. I only have 16k photos and it takes only 1 or 2 minutes. But during that time, the whole computer interface almost freezes due to a lot of IO on the HD.

I had the same problem with rhythmbox. I more or less solved it by using ionice to launch it. I can do it also for shotwell (didn't try for the moment) but it may/should be better addressed by the program itself. Don't know if you already worked on that issue?

Thanks

PS : I really don't understand the necessity for such a big scan (in a user's point of view, though I understand it may be better in a programmer's point of view). It should be optionnal (but enabled by default). If shotwell isn't synchronized with the filesystem, it's not a big usability problem for the user (he knows it's not synchronized!). When a discrepency is encountered by shotwell (file missing, metadata changed ...), shotwell can tell it to the user and suggest to launch a manual rescan.
