I am using Opera 9.21 and Java version 1.6.0_02 and connection has been very smooth when connecting through router to my ISP which has been servicing me for couple of years. Before yesterday I had to connect wirelessly through a hotspot across the street and to a different ISP.
That connection however was very slow and I was never quite pleased
with it. Qustion is: Have you at Caissa been doing some changes or improvements that supports this change I am experiencing?

Wish we could take credit for it, but I don't think we made any changes that would affect your connection.

OK whatever... nice is nice where ever it comes from. Seems smoothness for Opera 9.xx is here to stay... connection has been nice and easy now for almost a week and response time quite alright.
