on a 40-threads page, the addition on my Bulletin Board was 10-15 kb.

The total page, with images and all, without the preview is 129kb; with the preview it's 144kb -- total of 15 kb more.

Using gzip compression (which I do), the difference is more significant and at the same time less so:

without the preview the page (without images) is 8106 bytes (8 kb). With the preview, the page is 14,323 bytes (14 kb).

Maybe because we use gzip compression, no one has so far complained about the page loading slower. But it is a point to think about if you are trying to cut down on bandwidth.

I might suggest, though, that those users who connect with modems should edit their own options to include less topics per page. If they are on a particularly slow connection, they ought to go for 10 topics per page.
