pkgx adds 300ms+ to each invocation of a tool

[alecthomas]

This doesn't matter much for some tools, but for others that are invoked a lot such as eg. C compilers in a large build, or protoc+plugins with a large number of .proto files, this can really add up.

I'm not sure where this time is spent, perhaps it's Deno bootstrap overhead?

Should be fixed in the just released v1.2.0. If you get a chance please take a look and let us know. You will need to do a single --sync before the new cache is available.

Thanks, I gave it a shot but it seems to be roughly the same:

🐚 ~ $ pkgx --version                             
pkgx 1.2.0
🐚 ~ $ pkgx --sync                                

🐚 ~ $ time pkgx [email protected] version                
go version go1.23.0 darwin/arm64
pkgx [email protected] version  0.18s user 0.10s system 75% cpu 0.377 total
🐚 ~ $ time pkgx [email protected] version                
go version go1.23.0 darwin/arm64
pkgx [email protected] version  0.18s user 0.10s system 74% cpu 0.366 total
🐚 ~ $ time pkgx [email protected] version                
go version go1.23.0 darwin/arm64
pkgx [email protected] version  0.18s user 0.10s system 74% cpu 0.372 total

Hmm the cache cannot be working since for me eg:

$ time pkgx go version
go version go1.22.2 darwin/arm64

real	0m0.076s
user	0m0.053s
sys	0m0.018s

$ time ~/.pkgx/go.dev/v\*/bin/go version
go version go1.22.2 darwin/arm64

real	0m0.014s
user	0m0.005s
sys	0m0.007s

So still slower but not nearly as slow as before:

$ time ~/.pkgx/pkgx.sh/v1.1/bin/pkgx go version
go version go1.22.2 darwin/arm64

real	0m0.269s
user	0m0.198s
sys	0m0.042s

Note, I ran all a few times before posting these.

When you do pkgx --sync does it say caching during the output?

[alecthomas]

When not pinning the version I get a similar result to you:

🐚 ~ $ time pkgx go version
go version go1.23.0 darwin/arm64
pkgx go version  0.04s user 0.01s system 63% cpu 0.086 total

k can reproduce, this shouldn't be the case I'll figure it out.
