i already reduce the sensitivity of the web shield into (low)
but i do not try disable.

i understand that this new release is design for 64-bit system.

maybe for some users that using high speed net connection the reduce in speed is unnoticeable.

i did unchecked the "enable web scanning" and the speed back to normal.

Regards!!!!

 edit: i mean i did not try stopping web shield :D  i think "unchecked enable web scanning is the same as disabling :D " i am confused in using terms :D

Well I just used TCP Optimizer, which I have had on my system for years, but hadn't used it since I got broadband about 4 months ago. I used it to wring what ever was possible in my old dial-up.

When I set it to 20Mbits connection (it is actually a max of 40) and set it to optimal TCP settings, rebooted and ran the test again with the the web shield enabled, what a difference. My upload speed is restricted to 3Mbps/s  and download 40Mbps/s on my package.

You have effectively stopped the web shield if you don't have the "enable web scanning" option checked.

I don't know where you got the idea that this new release is designed for 64bit (not that that would make any difference to downloads/speedtest, etc.). Best not to speculate.

The only additional thing for 64bit is the boot-time scan. There have been elements for 64bit OSes for some time but it isn't a native 64bit version. It is a 32bit program version which can adapt itself for 64bit OSes when installed on a 64bit OS.

I doubt lowering the Sensitivity would make much difference as the traffic is still going to be routed through the proxy I have mine set on Normal (the default) I used to have it on high, just that I forgot to bump it up after a clean install after the beta trial.

Those on high speed broadband are possibly more likely to see a difference as they are going to be pumping more data into the proxy to be scanned.

I just ran a test on that XP SP3 link on page one with the web shield running and was getting up to 5MB/s download speed, when I did the snapshot it was reporting an average of 4.3MB/s which is the fastest I have ever had (after my TCP Optimize spell).

Tuning XP TCP parameters is a a black art and thankfully Vista and Windows 7 have fixed this.

DavidR, it looks like TCP Optimizer helped your connection speed ???

Yes, not so much the connection speed, but it looks like my old dial-up optimizations TCP Receive window settings, etc. were throttling my fast broadband connection.

i got that idea saying new release is design for 64-bit, because 5.0 is stable only in 32-bit and in 64-bit is incomplete. so .1 means they add only 1 feature in the program 5, and the last 3 number is the number of compatibility that has been solve :D
only my point of view :D

i am not familiar with TCP but i will try

Thanks!!!!

If it were a 64bit application, guess what, it wouldn't run on a 32bit OS.
