Any way to speed up converting large TIFs?

[ironywrit]

I have to batch convert a bunch of TIF images and some how rip normal sized JPG thumbnails for them.

Well, one problem I'm having is that identify and convert are both taking an enormous amount of time to run. I think it took an hour for a single TIF to convert, which is unacceptable.

I just need a thumbnail and a few intermediate images, all JPG ... not quite sure how to reduce the image efficiently. Like, how do you decrease both the resolution and the DPI?

Any help will be appreciated ... this tool is running from a server that converts on the fly from uploads ... so speeding it up is a great necessity.

try setting the size while reading in the input for jpgs. see http://www.imagemagick.org/Usage/formats/#jpg_read
