1. Re: Cache changes?
J McWilliams Dec 29, 2008 2:35 PM (in response to hrh gracie)I'd trash the whole thing at this point! Start afresh. I don't know if there's an optimum size for your O/S, or mine for that matter. -
2. Re: Cache changes?
hrh gracie Dec 29, 2008 8:29 PM (in response to hrh gracie)Been there, tried that. Unfortunately, it takes FOREVER to rebuild a catalog - at LEAST a day and a half. And the last time I did it (using 2.1) the thing started at over 500 MB and has grown back to over a GB in a month with less than a thousand new images....
No, the brute force and massive ignorance method isn't my choice in this case. There's gotta be a better way to optimize this thing. -
3. Re: Cache changes?
J McWilliams Dec 29, 2008 10:32 PM (in response to hrh gracie)Are you talking about the cache, or Previews, now? I wasn't recommending trashing Previews, the rebuild of which can take a long time for large collections, but the image cache, very different from Previews. -
4. Re: Cache changes?
hrh gracie Dec 31, 2008 7:37 PM (in response to hrh gracie)I was thinking you wanted me to trash the catalog and rebuild it. Do you just mean to delete all the cache files? I did that recently and so far LR has recreated about 300 cache files.
But my question is more about optimizing the space allocated for cache... how much is an optimal amount? -
5. Re: Cache changes?
J McWilliams Dec 31, 2008 10:16 PM (in response to hrh gracie)That I do not know, but figuring its optimal size is in some relationship to speed the OS has in going through the files to find what it needs, a fresh start should be beneficial. Any improvement? I doubt that setting it bigger than necessary is a problem, but there is probably a tipping point where it's too big for your O/S. If you're able and willing to perform tests, it'd be great to learn your results.
