Re: [Gimp-user] Debugging Perf on Linux

Thanks for that Elle, I followed up personally about the profiles.  
Going back to the list, one thing I should add is that currently for my 
workflow on the same machine I'm using Gimp 2.8 with the same sized 
images, same monitor profiles, and it works more or less okay.  I 
wouldn't say it's _fast_, and it gets a little crashy sometimes, but I 
think it's doing a pretty decent job for a single-threaded program 
processing buffers this big. It's miles faster than the 2.9 RC, so I'm 
guessing there's probably something other than that going on
