My Vim is kinda slow for nearly everything. Opening a file takes five seconds, it flickers when I move up and down NerdTree and sometimes when I switch windows or tabs, it freezes for dozens of seconds.
I have a lot of plugins enabled, plus webpack watch running. I have htop running on a separate monitor, and sometimes the 4 CPUs go 100% when I save a file(that's because of webpack), so this bottleneck is understandable.
But the others cited above are not. How do I get to know what exactly is causing these bottlenecks in my Vim? Is there a way to know this without experimenting disabling plugins, etc?
