Well, you can't do much with PvP unless you have a good FPS. To start being able to improve you'll need to get a better computer first (or upgrade certain parts of your computer) so that you'll have a higher FPS. Around 45 or higher is probably good enough, but if possible, then 60 FPS is definitely the way to go. Having higher than 60 FPS is good of course, but if it's higher than 60 then there's no noticeable difference as far as I can tell).

Here some ways that may help you improve your FPS without buying a new computer:
1. You can change your video settings in the options menu.
2. You can exit everything that is open on your computer except for Minecraft.
3. You can download a very popular mod called "Optifine" that many people use and is allowed on pretty much every server as far as I know (I haven't seen any servers that don't allow it).

If you do all three of my suggestions and you're still having FPS problems, then I would suggest getting a new computer/upgrading your computer.

Take a shower! Just kidding, When you run in minecraft, try jumping at the same time, it makes you go faster. Also, hitting an opponent while in mid air gives critical hits, which is why you should run towards your enemy while jumping. Don't worry though, Survival games is pretty though. Also, you should look up guides and more tips, and keep playing too, you'll get better.

Don't play minecraft anymore. Play a more useful game
