Bukkit

The issue I am having is an issue which involves the usage of of a fairly large users file & WorldGuard/Edit. Groupmanager also has this problem but PEX does not, unfortunately PEX is not an option due to other flaws. Using bPermissions causes WorldGuard/WorldEdit to have much higher usage resource than they should.

Which steps will reproduce this problem?:
1) Load up any build of WorldGuard/WorldEdit
2) Load up bPermissions with around 2k users
3) Run a timings and observe high usage from checking permissions when a player mines/interacts with blocks.

Here is a timings report of just one user mining with bPermissions: http://timings.aikar.co/?url=14455441
Without bPermissions the usage is minimal from WorldGuard/Edit.
A worldguard profile report shows the cause of the usage: http://i.imgur.com/PKvQofk.png
here is a profile from GM but the results are the same with bPermissions: http://paste.enginehub.org/89iua.profile

Which version of bPermissions are you using?: 2.12 Beta 6, also tried many older versions

Which version of CraftBukkit?: CraftBukkit version git-Spigot-db6de12-07c3001 (MC: 1.8.8) (Implementing API version 1.8.8-R0.1-SNAPSHOT), also tried older versions

Which OS?: Cent OS 6

Any other information we may need (plugins, configs, etc):

Multiple versions of WG/WE have been tried along with cleared configs.

Help with this issue would be very appreciated, we recently switched the PEX and that did not have the issue but it has other issues, groupmanager has been discontinued and I'm getting tired of lag issues as its plagued me for months. Willing to donate to the project if it can possibly be fixed.

I should clarify the timings I posted is from one user mining, a server of 20-40 people causes it to hit up to 50% of server resources.

Hmm, I appear to be able to reproduce the issue! Investigating the cause now.

@LaughNgamez: Go

Alright, can you try the latest jenkins build?> http://rymatemc.co.uk/jenkins/job/bPermissions/11/

It's changed how bPermissions checks whether a player has a permissions, and might help your issue. Judging by some timings, I've reduced the average time from 14.05ms to 3.75ms on my development server

This latest build seems to have improved a few issues - I've been using various java profilers to try and determine exactly where the issue lies. I've not had an awful amount of luck so far, however there are some improvements. Try it and see! http://rymatemc.co.uk/jenkins/job/bPermissions/17/
