Ok, so I'm having some problems in mc. whenever I change the direction im looking, such as just simply turning right, it lags like heck until I stop moving my mouse. My usual FPS is about 75, but when I turn, it's 2. I'm not joking. then, when I stop turning, it goes back to 75. Please help, this lag is an extreme burden for pvp.
Whenever you turn around to a certain side, Minecraft will start generating chunks in the way your facing. To fix it, simply turn down your render distance till it stops lagging. This is what I do when this occurs to me, and it may be a different problem, but this seems to be an easy fix by changing render distances.

First of all, you aren't experiencing lag. There are two kinds of lag. Input lag is when there is a noticeable delay between your input (such as pressing w) and the corresponding action taking place (your character moving forward). This is usually due to major bottlenecks in your computer, and usually only takes place in games that make use of all of your hardware, not ones that run in a virtual environment. I have experienced this once with a laptop that had a decent graphics card and a crappy processor. The N64 did this with many games. Then there's lag that takes place over a network. It can be due to the server being located on the opposite side of the world as the client, or due to lost packets. If you have ever been running forward and teleported backward, you have experienced lag due to lost packets. If you have ever been running away from an enemy, and thought you had a huge lead, but kept getting hit by them, then the server is likely on the other side of the world as you.

Anyway, the reason why you are experiencing massive framerate drops when you try to turn is basically because of what 18th_Dynasty said, but to elaborate on that, the actual cause, seeing as how you are playing on a server, is probably your ram. It likely isn't gaming ram, and isn't fast enough to swap the data in and out, so it causes the rest of your system to have to wait for it to finish what it's doing. This is another type of bottleneck. If this is the case, then turning down your view distance may make it less noticeable, but it won't get rid of the problem. I have pretty standard gaming ram, and I only experience this sort of thing when I overclock my view distance with optifine. If you are seeing it happen with normal viewing distances, you just need to get better ram. If you are on a desktop, it's gonna be a really cheap upgrade that will be really worth it, but even if you are on a laptop, it's a doable upgrade.
