Hi, Which one would you recommend we (VSCode) use?
Today, we are using cached data, but I wanted to find out if a startup snapshot would help us more. I've crammed all of VSCode's source code (except third party node modules) in a file and I've created a startup snapshot using `mksnapshot`. I would have thought that the startup snapshot would beat the current cached data usage on startup speed by a long shot... I was surprised to see that all of the time gains of using a startup snapshot (~200-300ms of code loading) is lost and then some while creating the UI (DOM and stuff...). It looks to me like the code that lives in the startup snapshot is fundamentally slower (50% or 100% slower), and that perhaps it does not use inlining? (see the deep stack traces below). 1. Before (using cached data) https://github.com/Microsoft/vscode/files/1724876/snapshot-before.cpuprofile.txt https://user-images.githubusercontent.com/5047891/36215842-80a615a2-11ad-11e8-9efc-2d0f2e533e07.png <https://user-images.githubusercontent.com/5047891/36215842-80a615a2-11ad-11e8-9efc-2d0f2e533e07.png> 2. After (using startup snapshot) https://github.com/Microsoft/vscode/files/1724877/snapshot-after.cpuprofile.txt https://user-images.githubusercontent.com/5047891/36216039-fcd8aa18-11ad-11e8-9bd4-fe4f1add9546.png <https://user-images.githubusercontent.com/5047891/36216039-fcd8aa18-11ad-11e8-9bd4-fe4f1add9546.png> Is this expected? Cached data is always faster than startup snapshot? We are on an oldish version of v8 (5.8.283.38), as we're using Electron 1.7.9.
