[sc-users] Bad leopard performance? Or something else?

[Batuhan Bozkurt]

I've totally missed the airport issue since I'm using tiger on a 
(ahem)hackintosh right now(without airport off course). I'll inform my 
friend, so he will try by disabling airport and I'm going to report 
back. And if there is a huge difference between activity monitor report 
and scmeter, I'll ask and try to file a bug report as Scott requested.

Thanks.
