I have gotten a few reports about lag on the CS:S servers. I personally haven't noticed anything. If anything, I may suggest that the anti-wallhack might cause the issues. It is said that it might use more CPU power of the server, but I haven't experienced anything like this. Maybe the effect could work on the players instead and draw more CPU power from them. Anyhow, if you do experience lag, please reply to this topic and tell how badly it is lagging, how often and since when did the lagging start? Before or after the anti-cheat update?
