Today I noticed my first problem with the Web Shield. I use Chrome as my browser in XP and it is at the latest version. At Speedtest.net with the Web Shield on, I can barely hit 6meg download speed. With the shield off, I hit 18 megs. I tried playing with the options and the only thing that made any difference was to turn off Web Shield completely. On this Win 7 64 bit machine, the problem does not exist and I get the same 18 meg speed with the Web Shield on or off in both IE9 and Chrome.
No problem here with XP and Firefox 11.0, just ran two tests (web shield on) on different servers and I get almost my max download speed for my 40mpbs plan.
Yeah it only seems to affect Chrome. IE8 shows no difference but only gets the 6 meg speed with the shield on or off.
