Making GD2 faster

[no]

I'm using PHP with GD2 to create image thumbnails, but it gets
extremely slow when processing large images (1600x1200 or more). I
had to raise max_execution_time to more than 120 secs and I don't
think my client is going to like that :( I guess I could switch to
bilinear resizing but it looks really awful.

Are there any tricks to speed up GD2 a little?

Thanks in advance!

I'm also interested, I found a faster CPU helped, and a little more ram,
but don't know if there is any tricks to it.

Try using imagecopyresize() instead of imagecopyresampled().

Yeap, that's what I meant about bicubic/bilinear resize. I'm using
bilinear now (imagecopyresized()) but of course quality is poor. I
guess that the GD2 libraries are not optimized at all cause Photoshop
or even Irfanview, Acdsee, etc. are a lot faster at bicubic resizing.

Consider using imagemagick instead. It's considerably faster for generating
thumbnails.
