I'am also using Ubuntu 16.04.
After the update I had some lags. I reset the whole config (deleted .config/sublime-text-3). I have reinstalled the plugins I use, but the lag was still there ( even without the config using a full config reset )
I checked Tools -> Developer -> Profile Plugins and have seen every plugin is in ms range exept for on_hover 15.808s total, mean: 0.025s, max: 7.877s
So I switched of on_hover functionality ( I do not use it anyway ) adding the following to my config:
Since I've done that, everything works as before. No had no more lags up to now.
Could you please check if you have something similar? Profile the plugins and check the values.
Here are mine:
