Slow inside VirtualBox shared folder about fd HOT 6 CLOSED

I'm not that familiar with VirtualBox. Do you know what makes these shared folders different? Do you run fd from within the VirtualBox?

from fd.

I forgot to mention that the host is a windows machine. Yes I ran fd inside VirtualBox but only inside shared folders the performance drops. They are pseudo-network redirectors (Windows Technology). My guess is, the way they get cached by the OS slows them down. Do you use a different access pattern then find?

I'm not sure. How did you perform these benchmarks? In particular, if there is any kind of caching going on, did you run an initial "warm-up"?

from fd.

I ran the tests from the README with a warm-up and multiple runs.

I'm also testing on a bigger data set now, where the slowdown is only 2x. (8 seconds to 4 seconds)

When I find time I will test the walkdir crate itself to see if the behavior persists.

Ok, thank you

@gitpy I'm closing this for now, as (1) I'm not sure how to reproduce this and (2) the internals of fd have changed quite a lot since you opened this ticket: directories are now traversed in parallel.

If you are still interested, it'd be great if you could re-run your benchmark and see if this is still an issue. Feel free to re-open this ticket, if this is the case.

Anyways, thanks for your feedback!
