Why is there sometimes lag?

[Rainyi]

I would be minning or doing whatever then all of sudden it freezing for like 1-3 seconds then back to normal? Nothing is wrong with my internet.

Try doing timings to see if the lag cause may be the server or maybe some client side issue. First do /timings on. Then wait until you get a lag spike and do /timings paste around 1-2 minutes after the lag spike. You can also just do it for multiple lag spikes if you wanted. You should get a link from the command. Then paste the link you got here.

Here is the timing sorry it took me a while.

There doesn't seem to be much tps loss on the server. Have you ever changed the tick speed gamerule on your server? If so try setting it back to 0. /gamerule randomTickSpeed 3 exactly since its case sensitive. Also there seems to be a lot of entities on your server. Do you have some sort of large mob farm that may be producing 500+ entities?

I will try the gamerule. We do have a pig farm on my server but it's not exaclty 500 pigs though it more like around 10 pigs.
