After the packages are loaded, there is a “long” time to wait until the first message indicate that the function called is running. Here is a test example: println("------------- Loading") t0 = time_ns() using LinearAlgebra using Random t1 = time_ns() println("Package loaded: ", t1 - t0, " ns")…

Julia has to compile the function upon the first run. When you call it again, it will be instant (within the same REPL session), but the first call will take a second or two to compile.

[image] maxchendt: You will see there is a time interval between “Reach main” and “------------- running -------------”, even in a consecutive run What do you mean by “consecutive run”? I’m guessing that you have stored all the code you posted into a file, and that you generate consecutive ru…

With the way you have setup your code, you are recompiling the function main every time you attempt to run your script. Try this: t1 = time_ns() println("Reach main: ", t1 - t0, " ns ------------") main() t2 = time_ns() println("Reach main 2: ", t2 - t0, " ns ------------") main() nothing…

[image] mkitti: Do not exit Julia. There are several cases: You are doing interactive exploration. Solution: use an interactive environment (the REPL, a Jupyter notebook, vsCode, Pluto, …) in which you leave Julia running. (For larger-scale code development, do this in conjunction with R…

I do wonder now that we have pkgimgs how long would it take to get scriptimgs . We seem to be getting quite close to just compiling this to a not very portable executable.

[image] mkitti: I do wonder now that we have pkgimgs how long would it take to get scriptimgs . [image] Taking advantage of pkgimages in 'scripts' Performance There’s a lot of benchmark scripts out there right now where Julia is at a big disadvantage due to compiler…
