add a section in the performance tips about not overly specializing on functions

This is a WIP to document best practices for cases where one wants to use the equivalent of a function pointer in Julia (specializing on the argument types but not...

I think the error here is in `compileall` at least: https://buildkite.com/julialang/julia-master/builds/36415#018f70db-0266-4177-b40c-6dd20f0f53b9 ``` From worker 14: LLVM ERROR: out of memory From worker 14: Allocation failed From worker 14: From worker...

Fix `JULIA_CPU_TARGET` being propagated to workers precompiling stdlib pkgimages

Apparently (thanks ChatGPT) each line in a makefile is executed in a separate shell so adding an `export` line on one line does not propagate to the next line.

Overallocation of arrays now seems to persist through precompile serialization on 1.11+

Creating the following package: ``` module OverAlloc function make_arr() x = Float64[]; for i = 1:175; push!(x, 0.0); end return x end const myarr = [make_arr() for x in 1:100000]...

Heap snapshot does not seem to work anymore on 1.11 (in chrome profile loader)

``` julia> using Profile julia> Profile.take_heap_snapshot("1.11.heapsnapshot") "1.11.heapsnapshot" ``` Trying to load this in Chrome leads to ``` An error occurred when a call to method 'buildSnapshot' was requested TypeError: Cannot...

allow setting the name/color/enabled via static expressions

The added test renders as:

This package does a more or less exhaustive combination of problems, algorithms and element types https://github.com/SciML/NonlinearSolve.jl/blob/d434b8d48086fa799ea344694c90a997dae22d48/src/NonlinearSolve.jl#L96-L98 https://github.com/SciML/NonlinearSolve.jl/blob/d434b8d48086fa799ea344694c90a997dae22d48/src/NonlinearSolve.jl#L137-L144 A total of 104 combinations of problems and algorithms are compiled in total....

Stdlib pkgimages seems to be compiled with generic target

Making this an issue so I can add it to the milestone: ```julia julia> cd(joinpath(Sys.BINDIR, "../share/julia/compiled/v1.11/Test")) julia> Base.parse_image_targets(Base.parse_cache_header("JfdTE_4EB71.ji")[7]) 1-element Vector{Base.ImageTarget}: generic; flags=0; features_en=(cx16) julia> VERSION v"1.11.0-beta1" ``` Ref https://github.com/JuliaLang/julia/pull/54093
