TPS

TPS, short for Ticks Per Second is a measure of how fast Minecraft mechanics such as redstone and farming run at. If a server's TPS is low, this causes what players call "server lag" which causes for normal functions of Minecraft to malfunction.

TPS should not be confused with FPS, Frames Per Second, which is the measure of how fast the player's computer is rendering the game of Minecraft entirely, while TPS is usually recognized as the FPS of a server, in which measures the speed of how fast the server renders Minecraft.

Relating to 2b2t
The TPS of 2b2t has always been terrible, even during its early years. There are two main reasons for this bad of TPS: server issues and players (this usually being the biggest reason).

Server Issues

 * Very old hardware (Running for over 6 years)
 * Players joining
 * VERY LARGE MAP (worth over +2700 GB's)

Player Issues
2b2t is usually at an average of 20 TPS and is usually considered a miracle if it is above it. At 20 TPS 2b is still playable and normal game function works perfectly fine. However, players can turn on lag machines or use some sort of exploit that can slowly drag down the TPS to even levels below 1 TPS. This causes many of the normal functions of Minecraft to lag extremely, making things like breaking blocks a pain in the neck without god tools. Even with god tools, low TPS can still be a bit annoying as breaking blocks will cause the phenomena known as a "ghost block" in which a block appears broken and players may go through but in reality is still there and can cause for the player to glitch out in it or not allow for block placement near it.
 * The use of lag machines
 * Generation of chunks (from little to extreme amounts through exploits)
 * Doing things that normally lag Minecraft (i.e. using redstone, detonating TNT, creating cobblemonsters, etc.)

The low TPS may also cause the phenomena known as the "rubber banding effect" on players. This phenomena is caused when a player moves and then is randomly placed, at any given time, in a sort of limbo where players cannot interact with blocks before being launched back to where the player first began moving before the random occurrence.

Sometimes TPS on the server is so bad that it can even render the server unplayable and can cause an uproar in chat with several messages complaining about the lag. If the TPS hits 0, the server usually restarts and kicks everyone back to queue.

Player Reaction
Players on 2b have varying opinions on TPS. Some think that surviving the TPS of 2b2t is a right of passage and only true players of 2b can withstand the annoyance of lag and continue to play through it. Others complain and joke about it, calling Hause a lazy sack of shit for not fixing the lag. Several oldfags claim that they have become used to the bad TPS and have accepted it to be a normal part of 2b2t while several newfags complain in chat and call the server a slow piece of shit that is barely playable. Players of 2b usually joke about bad TPS being something that weeds out the worst players. All in all, bad TPS, as annoying as it may be, is a common phenomena on TPS and will continue to test the best and weed out the worst.
