the Gimp and pre11

the Gimp and pre11

[Ed Tomlinson]

Hi,

Is it just me or is the Gimp visibily slower with pre11 compared to pre10?

I am editing 6 Megapixel files (2800x2048) and things like rotations seem to 
have delays that were not happening with previous kernels.  My box has 320M.
Seems that pre11 does not swap out as much as pre10 so Gimp has less to work
with.

Since GIMP uses it's own memory management using a tile approach I
hardly doubt this is caused by swap usage if you defined the maximum
amount of memory GIMP should use correctly; though it may be that the
kernel swaps out tiles that the tilemanager considers to be active (and
thus in memory) this behaviour should not happen as long as the kernel
is not to eagerly swapping out memory and considering that the tiles
are referenced quite often it should not swap them to disc at all IF
the recently introduced algorithms work correctly.

Anyhow, just to make sure, would you please mention much memory you
assigned to GIMP and what else is running on the system?

Also, try a test with pre11 with swap turned off, and see how that affects
your system.

Please note: I am not recommending running without swap under normal
circumstances...
