Filesystem performance on macOS 10.15 #27

Open unsignedint opened 4 years ago

unsignedint commented 4 years ago

Firstly, I think this looks like a great project and it's good to see an alternative in this space!

I finally got around to testing vctl on Fusion 11.5.6 (macOS 10.15.6, MBP 2018 32GB i7-8850H) in comparison to Docker For Mac. These are some typical build times from clean for a nodejs (bucklescript, actually) project, 2 CPUs and 8GB RAM assigned to the container VM.

Native: 2s Docker for Mac (osxfs): 10s Fusion/vctl: 30s

I'm not sure if there are any tuning or filesystem-related knobs we can play with?

Not presently, but maybe @jeffwubj would have more insight. I know that we're doing a lot of performance-related work in the upcoming Fusion 12 release, but I'm not sure how many 'knobs' we expose...

I'm also seeing terrible fs performance on macOS Big Sur with the latest VMware Fusion.

This seems to impact both volumes and the containers themselves, for example javascript-obfuscator, a node.js project with many dependencies takes about 8 seconds to even show the help on CLI compared to 0.2s on macOS native.

in vctl container:

root@php:/app# time /usr/local/bin/javascript-obfuscator
Usage: javascript-obfuscator <inputPath> [options]

[output omitted]

real    0m8.319s
user    0m1.328s
sys 0m0.294s

on macOS:

❯ time /usr/local/bin/javascript-obfuscator
Usage: javascript-obfuscator <inputPath> [options]

[output omitted]

/usr/local/bin/javascript-obfuscator  0.26s user 0.05s system 104% cpu 0.293 total
