I have done extensive testing with plugins and it appears that the latest vault causes a lot of lag. I disabled pretty much everything but vault and it's fine but as soon as I add vault it lags like crazy. I downgraded vault to 1.2.6 and everything is fine. Using latest craftbukkit R4 (same issues on R3).

We are running on a 4-core i7 machine with 24 GB of RAM. Is there something that was changed from 1.2.6 to 1.2.8 that would cause a plugin hooking into it to cause more than normal lag? The plugins we use that use vault are BoosCoolddowns, CouponCodes, TreasueHunt, and WebAuction.

We do a lot of lag testing ourselves, Vault never shows up in VisualVM nor does it ever get tracked as having any methods that cause CPU issues. On top of this the JavaVM optimizes calls that get repeated, making it unlikely that Vault is actually causing any lag, and more likely a side-effect of plugins that are hooking it.

Are you running on a single-core machine? Without actual stats on CPU usage or some statistics showing Vault with higher CPU in something like VisualVM there's nothing I can do for you.

shouldn't, what Econ are you running?

it may possibly be iCo6, it still uses old events, do you have anything that interacts directly with iCo?

unable to verify

Thank you for the replies. I just realized that the new mobarena uses Vault, it might be the cause. Thank you for helping to check into this issue.
