When is 1.10 expected? Just wondering I did a quick google and it seems a lot of the 1.9 improvement were back ported from 1.10? Or is that really 2x on top of current 1.9?

1.10 feature freeze is going to be in the next few weeks. after that it will be a few months depending on how much is required to fix all the bugs that have probably been introduced. 1.9 mostly doesn't shorten loading times (although weak dependencies end up helping a bit). 1.10 has had a bunch of load time optimization which became a lot more obvious once 1.9 got rid of all the stupid stuff. the exact speedups are package dependent, but 2x is a good estimate. some packages get a lot more, some are about the same.

Thanks. Exciting times for Julia!

So ~0.85"?

Python is not compiled and start & load pandas (which is comparable to the libraries loaded in the article) in ~0.4" on my computer, and that's a notoriously slow language.

If I were to use e.g. Rust with polars, load time would be virtually none. And when I have to process ~50k different datasets, I can't afford 0.85" per file, which would translate to ~11 hours of overhead.

It's not 0.85 per file. It's 0.85 for the 50k files combined.

No, because the program has to be run by slurm over several compute nodes, so it can't process them all at once.

as long as you don't have 50k computers, it still should be 0.85 seconds per node which is still tiny.

> it still should be 0.85 seconds per node

No it's not, because I will not architecture my whole pipeline & program around Julia inability to start in a second, I will just use another language.

In good company, that is what Python folks do all the time.

Python does not take 1.7" to load pandas.

Hello C, C++ and Fortran.

Because you're compiling...

And if you need to do the same in Julia, you should also pre-compile or some other method like https://github.com/dmolina/DaemonMode.jl (their demo shows loading a database, with subsequent loads after the first one taking roughly ~0.2% of the first)
