maps/page size How big is TOO big...?

Hey guys I'm using Roll20 tonight for our first session since switching over from Hangouts. Everything is working fine as far as setting up on the GM side and prepping. My concern is I have 6 players showing up with varying connection speeds and so forth. When setting up my maps/pages how big is TOO big as far as page size? I have one wilderness map set at 75 x 75. I have a very good internet connection it's zippy. But it's just ME at the moment online. I'm worried about load times and screen refreshes with all seven of us. Just wondering what others' experience has been. Any suggestions on limits on map sizes would be greatly appreciated. I'm hoping to avoid any suprises/hiccups tonight. Thanks.

Hey Jolly – cool seeing you here. 75 x 75 sounds awfully big. What resolution is the image, and how zoomed in are you planning on getting? I've used the default map size of 25 x 25 before with a map filling most of the space and it loaded pretty quickly for everyone. I had the image set to 150dpi so I still had a clear map when zoomed right in to 100%. Of course, it all depends on your players' connection speeds and how fast they can get the info from the Roll20 servers. Thanks for KotDT, by the way. Cheers, Rob.

My maps are Much bigger than that (10x) and there have been no problems other than getting tokens lost on the map.

thanks guys. I'm at 100 dpi -- hopefully i'll be fine. I'll find out in a few hours. And thanks for the KODT shout out, Robert. ;)

Game ran with out too many hitches. The main hiccup was Opentok didn't seem to be working when we all logged in (nobody's cams/mics would activate). We fell back to running Roll20 via HangOuts and every time pretty much ran smoothly. One player had some problems getting booted once toward the end of the night but he admittedly has 'crappy internet'. We also had two more players join us (for a total of 8) so that could have had something to do with his problems. But overall the larger maps with lots of tokens didn't seem to be an issue for us. Not sure what was up with Opentok. I checked the status board and it indicated they were having technical issues so I'm just going to assume it wasn't anything on my end. Looking forward to reading the optimizing-piece.
