How come texturetool is so slow?

How come importing 7.7Mb of 1024x1024 TIFF or PNG takes 1 hour on a 1 year old iMac?

I look at the process and it takes 665Mb of memory and 100% processor for 10 seconds to work a single image.

And how come when you want to compile the game for iPhone it starts over and re-import everything...?

I feel okay with bumping this after a month since that necro brought it back after 8 …

Having what appears to be the same issue with a PC project we’re trying to get working on iOS. Unity likes to reimport the assets and that takes something like 4 to 6 hours, during which production obviously grinds to a screaming halt. It’s a big project, granted, but that same full project import takes maybe 5 or 10 minutes on Windows. Sadly, I’m not seeing that many people with the problem so it’s been very hard to research a solution.

Anyone got any tips on how this could be improved? I would greatly appreciate it.

Just tested this now so I can reply without fear of being wrong:

It doesn't or actually, it shouldn't really. Importing a similarly sized file takes less than 20 seconds on my Mac. Something wrong with your mac maybe ?

From what I can tell, it doesn't. It just looks for and re-compiles the scripts and adds and builds the scenes.
