The script apparently put allot of strain on the computer viewing the page. I got
50% CPU load with 19 snow flakes set in the script and running on a laptop Intel centrino DUO 2Ghz and 1 Gb ram. It is obvious the script since if I close window it drops to 3%. Funny : opening first page several times in the same time it does not increase the CPU usage !
I don't know what load put on the server as is was mentioned before. I have 10-40 logged in users and approx 20 guests most of the time on the forum. Can this be called large forum ? (my guess is not)
I cannot asses what strain the script is putting on the server.
Already have received good impressions about the snow

Thanks for the mode.
