- 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.
