Honestly, I love the gamemode and all, and I know there is a lot of lag that is hopefully getting fixed soon but, I can barely pvp in this game. First off, when hitting the zombies, the hit detection is so slow it's like 1 hit per 2 seconds and for the zombies it's not as bad when going for humans. The disguises also cause lag to the server, so if you dont have good GB/Ram on the server, that could be the reason why it's lagging a lot. To end this off, the suggestion is to remove the zombie disguise as it's harder to hit/pvp with in addition to reducing the lag. You could do this, or simply add a large amount of ram to the infection server.
You made this thread less then an hour after infection released, of course it's going to be full of lags because there's nearly 100 players on. Its already died down and is much less laggy, no changes are really needed.
I'll see what I can do, the only thing I can think of is the disguises interacting with it for some reason. I think the gamemode with player skins rather than zombies isn't very appealing though.
Support! It's not that bad without the skins. If it fixes the lag maybe it's worth it. I mean we dealt with non disguised zombies for many years and I don't remember anyone having a problem.
