(edited to add both the STATUS BAR and PANEL must be hidden for speed increase)
I recently noticed that my project builds substantially faster with the Panel and Status Bar hidden. I hid the Panel the other day and noticed a huge performance increase. I pretty much use default tsconfig.json configuration. Wondering if anyone else can recreate?
Timing with panel open: 19.86s
Timing with panel closed: 4.60s
It appears the Parse Time, Bind Time and Check Time are much faster with Panel and Status Bar closed.
The steps I use to build:
- CTRL + SHIFT + B
- Select "Build Project"
- Panel opens by default
- Close Panel with CTRL + J
tasks.json
{
"version": "2.0.0",
"tasks": [
{
"label": "Build Project",
"type": "shell",
"group": "build",
"problemMatcher": ["$tsc"],
"command": [
"tsc -b --extendedDiagnostics project/tsconfig.json"
]
]
}
Output of --extendedDiagnostics with Panel open (edited same file to recreate build):
