I surely agree that the main factor on the usability is SD access, but an increment of 5% on the libs and apps could be useful too.
Evenmore if the only work for us is to add some new flags to the compiler or build a new version of it.
Also note that as I mentioned before, pcc doesn't compile for linux+arm+elf nowdays.

Next is if it makes sense to save 10% (maximum) of this time. I have seen memory sticks taking a lot of time when 'switching banks' currently I only measured on the emulator. The real DR might show that most time is lost in SD-card access.
Also things like the size of the database (global.db) might play a role, since thumbnails are also stored there.
Iņigo: you reported the issue with the unresponsive Book-view, can you tell a little more about how the Book-view mis-behaves and the size of your global.db file?

I can't provide any real data now because my DR800 halts when I access Books atm.
But if I remember correctly, I have ~3000 books, global.db size is ~28MB and it lasted ~20 or 30 secs in showing me the first page.
EDIT: 3680 rows in global.db, 31 seconds to show Book folder, 27.82 MB
I'm moving my DR devel env from a VM to my real desktop and I'm building a new cross-compiler now too. So I'll try to come back with some numbers early.
