Minecraft lagged after PC reboot?

I played Minecraft on GommeHD.net 2 hours ago without any laags, bugs, etc. Now I have turned my PC on again, nothing happened while it was happening and now it feels like gummy hell and I stood there all the time. Screens have already checked everything in MC and at LabyMod everything as before but it feels like hell could you please help me quickly?

I would be extremely happy about an answer

Do you have these Laggs in the SIngle Player?

Hmm let's see

It may be that it is due to Labymod.

Start Minecraft with its Optifine 1.8.9 version and see if it lays.

Hoffe could help.

Ok thanks the laags are actually like before without labymod but like to play with LabyMod because I want to play with voice chat…

You can allocate more RAM to the game then it will not lodge anymore. Google after "Minecraft RAM assign":)

OK thanks.
