Thanks Johannes and Jose,
Just to make sure I understand - the size setting in the options impacts
not just how much RAM Is allocated for thumbnails when DT is running - but
also how many thumbnails are cached to disk? That seems a little odd to
me, since I have a *LOT* more disk than I have RAM, and I'd be happy to
allocate 10x or even 100x as much disk to caching thumbnails as I would
RAM. Has any thought been given to that?
If I get a chance tonight I'll try building the latest from GIT and try out
the exif thumbs.
I'll also try the cache_compression setting...
Thanks again,
Warren
