Since the Netcode Testing thread was locked I'll post this here, not sure if anyone else has noticed this.
I did a test between myself and my brother in KOF, in the same city on Vancouver Broadband. When initially connected via my Router it showed us as having a 3 Bar Connection, which we found very strange as SSFIV always shows us as 4 Bars Green. Then I decided to go right from my Cable Modem to my PS3 and it changed to 4 Bars in KOF. The bad news is that even when it shows us as having a 4 Bar connection the game still had noticeable input lag and didn't feel any better than when it showed a 3 Bar connection. It's actually shocking how bad it is under optimal network conditions when you do side by side tests with SSFIV.
SNKP, please fix this.
