The following is an e-mail I received today from Ryan at DiscoverStation. Rather than try and paraphrase his comments I am just posting the whole thing. I think this spells it out rather well but if you have any questions please let me know or call Ryan.
Your library staff can turn off the Internet filter if they want to, I believe our support staff got confused about one of our newer features.
The new feature is called “Performance Filter”, and is configurable in Network Personalizer (this is the program that Mindy runs). I checked your session profiles, and they all still have the performance filter enabled. This means that if a patron, or library staff member turns off filtering during a session, the performance filter will still be on.
What Performance Filter does is blocks web pages that cause known problems with multi-station software. The biggest culprit is Flash Games. Adobe Flash Player can behave very badly and cause the computer to run extremely slow when more than one complex flash animation is running on a computer at a time. We have written bug reports to Adobe and are doing everything we can to help them fix their software, but they are still months away from a new flash player.
We update the list as we learn more sites that cause serious problems with Adobe Flash Player, right now the sites we block for performance reasons are:
2flashgames.com
addictinggames.com
arcadetown.com
creaders.net
flashplayer.com
freeaddictinggames.com
gamesheep.com
games.yahoo.com
heavygames.com
kraloyun.com
miniclip.com
mofunzone.com
mousebreaker.com
neopets.com
newgrounds.com
outwar.com
runescape.com
spiderriders.com
xgenstudios.com
We are aware that some peoples pages on MySpace cause performance issues, but most of the site doesn’t, and almost all libraries don’t want to block all of myspace, so we don’t include it in our performance filter.
If your staff continue to experiance performance problems, please let us know the time and computer which experianced the problems and we can modify your filters to include the sites that may be causing the problems.
