Its the ticks per second your computer (or the server you are playing on) is running at. For a full speed world it has to be at 20tps
http://www.minecraftforum.net/…6-ticks-per-second-v0411/
can help keep an eye on how laggy your server is getting and can help diagnose if mods are causing lag (Mostly via trial and error)
I doubt a low tickrate would cause your electrolyzer issue though
Hmm, perhaps greg needs to add a little condition to not start a new process till at least 500 or so EU are stored in the internal buffer
I cant replicate the problem is all, do you know if your tps are at 100%?
Hmm, grab an EU reader and check the cables and the machines, see what they are getting in. That tool is underrated at finding issues in a line.
How far away was the electrolyzer from your MFE?
What type of cable are yo u using between it?
Are there other machines on the same line?
Edit: I am going to assume gold cable at a range of anything more than 2 blocks, if the power supplied is anything less than the required 128EU/t (Even 0.5EU/t less) once the machines internal buffer is worn out it will stall.
Try upgrading to Glass fiber cable, make sure nothing else on the same line is drawing power, or add a batbox to the same line (In parallel) it will supply any power droop your system may be having.
Skid you can normally use Electrum in circuts as a replacement for redstone, the result is more circuts as well.
I have been thinking about external liquid cooling for reactor vents similar to a build-craft combustion engine.
A block that is able to be added to the outside of a reactor that directly drops or maintains the hull temperature of the reactor it is attached to using coolant such as ICE/Water/Coolant
Before anyone comes along with the "Coolant needs to be hot" line again, in a reactor you have
Reaction > Really hot coolant loop > Steam generation (Which gets sent off to turbines and cooled)
However if that steam generation loop is not sufficient to cool a reactor there are other things that are in place to help cool should the need arise. These coolant methods are not the closed loop that runs inside the reactor, and seeing as the reactor is completely enclosed (produces steam and has cooling vents) It is safe to assume it is not a 100% accurate to life simulation, thus allowing for external piped coolant to be used in order to maintain hull integrity.
I also know this description is stupidly oversimplified but I noticed you have plans for your freezer and reactor cooling and thought that idea might have legs.
I would also love to see a few extra uses for lead other than reactor plating and batteries.
I am thinking lead paint as an alternative for flax seeds in rp2 paint cans
Using lead dust as a replacement for pipe waterproof on buildcraft pipes
Lead dust as a replacement for redstone in basic circuts (solder)
A Lead Condensor for nuclear reactors (Based loosely off a lead cooled fast reactor setup)
Could also be used as an additive to fuel for that smoother running engine and extra environmental damage
I would love for there to be a lower teir version of the quantum chest (Not factorization barrels, I really do not want to install that) but a replacement for a 64x64 stacker. I use 5 chests for my quarry system to siphon off select items and 1 for my UU matter crafting system
Hehe i know that feeling, I dont use turtles, was a decision that made some people not too happy but its resulted in a better feel on the server, same for no thermal expansion (Different reasons, too long to go into here)
On my server I dont think i have seen anyone use a geothermal in the nether, there is a really heavy emphasis on nuclear and green energy. What I do have in the nether now are shitloads of centrifuge stations processing lava into tin/copper/gold/silver/tungsten.
Best use of lava on a mass scale, 40000 lava blocks makes alot of materials, really saves costs on those circuits and diamond use from glass fiber cable.
I do also have a quarry world (Just a flat-world Plains with no ore increasing modifiers, quarries are allowed to go wild there. none in the overworld.
If i was going for a larger server I probably wouldn't be using nether ores and would be disabling Cooperite generation in the end.
But it feels very nice with 2-3 people currently. After the first stack or so of Iridium plates things ease up with green gen farms and whatnot.
Most of my iridium still comes from overworld mining.
I do feel that water mills could use a buff for both their passive and manned power, they are no where near what a wind farm can produce or even a solar farm.
The best unmanned setup of water is 0.25EU/t at an optimal setup per unit, meaning 4 per EU/t
They just feel... sad
I just hate the rain so much though 
Edit: Just thought I should mention, Powercrystals now does the nether ores mod again so you might wanna just check and make sure there is full compatibility with it as it now adds a few extra ores.
http://www.minecraftforum.net/…s-and-more/#entry20092612
Im just installing to see how it handles currently.
Edit: Most things work fairly well, but there is no handling of nether lead ore.
With a clever setup of Thorium/Plutonium Reactors and a decent breeder you can get a steady 10k EU/t for matter generation well before fusion. Automation is your friend, i couldn't imagine doing large nuclear farms or most things without automation in both the crafting and maintenance.
You hit the nail on the head (It was late when i posted that last post)
Edit: So I have been fiddling around with a Logistics Pipes and Liquid UU crafting system and just ran into this error.
http://pastebin.com/FEEVEvPF
Here is the full log.
The error occurs when entering an area where the accelerators are sitting. It did not occur in the few hours of setting up the system. Just when somone else moves within range or when somone in the area logs in.
Edit: Upgraded the server and client to 1.4.7 and things are working smooth again.
Why you removed ability to craft Calcium Carbonate Cell from Calcium Cell?
Im gonna guess that it was something meant to move to the chem table but just got forgotten.
You might be interested in getting in contact with denoflions. I have a feeling some of the work he is doing with his PFF mod may be very usefull to help automate what you are doing.

Rather than relying on other mods to supply the comparability he has opted for the user finishing off compatability.
Krugle, have you checked for an ID mismatch
The ender pearl dust for portal gun is smelted in a furnace, gregs dust is macerated, there is no conflict of the two.
It was the method i first used to kill the wither
I should also add its best to do it in a cave (The wither can shoot a bolt that breaks anything when its idling) using obsidian contains it when using its normal bolts.
