I get a ton of the
[WARNING] Can't keep up! Did the system time change, or is the server overloaded?

So essentially everything runs just fine until we start getting over 25 players on the server (on 440, we were handling 50 without a problem) . Once it gets over 20 players or so, the CPU stays around 100% with the memory at 85%. It doesn't drop until there are under 15 or so players, and then it might come down to about 60/40.

The interesting thing is, is there is no lag in the chat, or lag with breaking mushrooms, flowers, torches, etc.
However, breaking regular blocks takes up to 5 to 10 seconds, sometimes with the blocks even reappearing. It also seems to spike more when players are logging in and out.
WorldEdit's Superpick however, has no lag in breaking blocks, and they pop off like normal.

 

I get the feeling this is a 1.3 problem, Buxville has supposedly patched it but the fix has (somewhat understandably) been kept under warps.

 

Well I saw others commenting on it, (which by the way, with like 5 players on its at 76/27) and saying they had a squid problem, but that doesn't seem to be the issue with us. I've looked around and squids spawn in their normal 3-4 squid packs, spread out. And using butcher or bmob doesn't provide any relief.

 

This block lag has been effecting playability on my server as well. I'm fine up until about 30 players and then it starts to get noticeable. At 60+ players, its definitely a complaint. Before Bukkit updates, I was able to run with no problems what so ever. I was peaking 80+ players, zero block lag.

Chat isnt' effected at all, so it is not server Lag.

 

Holy bajeezus, what kind of hardware are you running on?

 

Same issue here. I can Compass warp around no problem, and chat is fine, but block breaking is very laggy.

 

Just curious, if any of you are using WorldEdit, do you notice the lack of the lag (not with everyone, just the person using it) when using the super pick to bust blocks?

 

@Orcworm
Buxville still uses hMod and the patch it uses is a fix for hMod itself not a fix to bukkit or the MC server. Just so you know.

 

Well, that's that plan out of the window then ;p.

 

*shakes fist* wheres the fix!
