8 years ago This only happens on the first execution of rustup, so it's likely related to disk access which is then being cached for later executions. While I can't reproduce it taking 3 seconds to run, it is noticeably slower on that first run.
These are the minimum steps that need to happen:
rustc rustup proxy is runrustc is runThere are a few factors that might contribute to slowness, not all of which can be improved easily:
Hopefully it's the last one, in which case it should be fairly easy to track down with strace.

8 years ago Ok I did a strace -rTC:
After you can find all command's output but from what I can understand just follow two lines mater:
0.000046 wait4(2458, /home/mdamico/.multirust/toolchains/nightly-x86_64-unknown-linux-gnu
[{WIFEXITED(s) && WEXITSTATUS(s) == 0}], 0, NULL) = 2458 <4.981381>

Hi!
Looks like sometimes
rustc --print sysrootcan take as long as three seconds to complete. I think this a bit too much, and I suppose that rustup is to blame. See https://github.com/intellij-rust/intellij-rust/issues/754#issuecomment-255958020 for example of this issue. We've raised timeout to five seconds in IntelliJ Rust, so this shouldn't be a problem, but it seems fishy anyway!Many thanks to @la10736 for investigating this issue!
