My forum gets about 20k posts per month. I'm wondering if there are any GF sites with 20k+ posts per month? I'd like to see if the forum can run smoothly at that level.
I'm not sure on specific traffic ... but I know from personal work on the site, that it has a LOT of traffic =)
This forum is also a very good example. I'm not sure on specifics again, but I know that this forum receives a huge amount of hits every day, let alone every month =)
I'm not sure how helpful that's been, but hopefully it'll show you what GForum is capable of
If you go to dropzone.com's forum search page and search for posts made within the last month you'll see they have over 50,000 ...so I'd say that 20,000 per month is no problemo!
