Re: [K12OSN] I need to make Flash work faster....wanna pitch



Thanks William,
I'll give the drivers a try.  I'd say that since I couldn't log in at
the server itself that it was cpu related.  We have a gigabit backbone
with bond0 using 4 nics. I wonder if there is a way to disallow the
"high quality" mode in flash?

I there a special blacklist having to do with this?

I did. That's how I came up with 70% for the culprits.  It's pretty
much any game on the Disney site.  Could someone try this one so I can
compare?

  I wonder if the nice could be applied to this problem.  Is there
away to make the flash plugin show up as a process to be niced?


Thanks,
Peter
