Hi,

I'd say it's slower than a normal user can cope, especially when zooming.

I have an OL (current SVN version) web site with a WMS base layer (tiled) and 
a WMS alpha=true layer (not tiled). If I use IE6 and I try to zoom (small 
click on the little + button), my navigator will freeze for some random time 
between 3 and 60 seconds.

By freezing, I mean not refreshing the navigator window, not using CPU, just 
doing nothing.

If I remove the alpha=true, then the website works like a champ appart from 
the transparency being broken for my non-base layer.

Sorry, no public web site to show. But I attached a PNG returned for my second 
layer (in attachement). 

My current solution is not to use alpha=true at all. If you have to support 
IE6, better switch to GIF and forget about alpha channels and the added 
quality.

CU.
