Great! Not or what.
TTFP is essentially instant. And many other great improvements.
So much work has been done over so many releases, so with no disrespect to those release I will say that 1.9 is the best since 1.0.
Awesome reward we all got for sticking with Julia.

And 1.10(dev) is even _more instant_

1.8 was, 1.9 is, and 1.10 will be the best release since 1.0 š
(Joking aside, I certainly agree that 1.9 was an important leap.)

Are you speaking from PERSONAL experience or are you thinking wishfully?

The new command line option `--heap-size-hint` in v1.9 makes it much easier for me to run jobs on shared clusters without running out of memory. You can tell the GC how much RAM you actually requested from the clusterās queue system, rather than the total memory of the nodes running the job.

Hi,
Iām surprised by your timing of plot on 1.9.0. 2.8 seconds seems a lot. For me itās less than a second. Are you on Windows?

Yes, Iām on Windows. But my timings are for GMT.jl plot, not Plots plot. And also mind you that @time alone, at least for my case, does not report the true time.
_e.g._ in 1.9
```julia
julia> @time plot([0. 0.; 1. 1])
1.015570 seconds (3.47 M allocations: 212.676 MiB, 7.15% gc time, 99.74% compilation time: 87% of which was recompilation)

At what line of work are these latency improvements attributed for `v1.10` ?

Mostly just a bunch of profiling and fixing the expensive parts. see [Pull requests Ā· JuliaLang/julia Ā· GitHub](https://github.com/JuliaLang/julia/pulls?q=is%3Apr+is%3Aclosed+omnipackage) for a list of a decent chunk of them. (omnipackage was a package made for benchmarking loading issues that just includes a couple thousand packages including the DIffEq stack, ML stack, Plots, and a few other things)

So itās language improvements, not just package improvements?

There might be some package improvements, but there have been pretty substantial language improvements for load time.

Package improvements would probably impact both 1.9 and 1.10 (but might not improve 1.8, e.g. switching to PkgExtensions, caching more in the package image).

I was surprised by all of the replies to my post. Perhaps my use of a vernacular expression was confusing.
I only intended to give the Julia developers and contributors a well deserved congratulations and āpat on the backā.
