I knew VSCode was very optimized for an Electron application, but you have no idea how fast this is. This is faster than my Vim set-up, and I have taken my sweet time making sure Vim only loads the plugins it strictly needs and I try to switch to the asynchronous version of a plugin as soon as it pops up but still, VSCode is more consistently responsive for a lot of tasks.
I'm not sure wether I'll make a full switch yet, specially once I get a proper computer back, but the quality of the plugin ecosystem (I thought vim-go was amazing, but VSCode's Go plugin is just ridiculously good and properly asynchronous) coupled with this huge performance surprise are really making me consider it.
On my system, the new parallel file search from VS Code is an order of magnitude faster than Sublime. For example, searching my entire project is 2 secs in VS Code vs 20 sec in Sublime
VSCode is apparently faster than Atom, and I sped Atom up considerably by disabling languages that I rarely/never use. Timecop plugin does wonders for tracking down the slow plugins
