Towny Permissions:

PermissionsEX File:
- A bit messy, but that shouldn't cause any lag related issues. Also, we have 
multiple worlds (One for factions, one for towny), but certain plugins are 
disabled in certain worlds.

To add, the eximation file: 
http://files.enjin.com/295576/Server_exam/2013_03_04-5_23_41.exam (This is on 
the enjin servers, shouldn't cause you any viruses or whatever. Use Nolagg.jar 
to open).

I don't usually download .exam files. Can you pastebin.com the findings/the 
bukkit timings?

(And for the record, we don't use NoLagg. It was just to examine the server 
while I turned all the NoLagg's features off)

All you need is the nolagg.jar on your desktop, start it and load the .exam 
file!
The file is encoded and is not readable by pastebin.com, but if you want it:

Alright, now Im sick of it. Its been 1.5 weeks without a response from the 
Towny team. Thats rediculous. I want answers!

I just updated to 1.5 and my CPU is at 60% with no players online. Towny is 
using 5044ms on my server (According to Nolagg Examine). Thats rediculous.

Show us the bukkit timings file. I trust that more than nolagg's examine.

I'm also experiencing high CPU usage with Towny. I ran a plugin check using the 
builtin "/timings merged" command and found that Towny had over twice the 
execution time of any other plugin installed. It's using almost 3 times the 
processing power as WorldGuard with over 50 regions.

Also noticed that the Towny MySQL storage seems to be somewhat inefficient, and 
that my the TOWNY_TOWNBLOCKS table is incredibly overgrown. Not sure if that 
may be the issue?

Here's a link to the pastebin of my timings file. I have moved the Towny 
portion to the top to make it easier to find.

re: mysql, there's no reason to use it unless you've made a webgui for towny. 
it is no slower/faster than flatfile.

Also please update to 0.82.1.11, it includes a change that will decrease the 
BlockPhysicsEvent which was showing a large footprint (even though it was not 
doing anything if you have the reverts turned off.)

If you could show us the timings after you update that would be great.

Those timings look absolutely fine.
