I took a look at this issue. It looks like just populating the attributes
itself takes time. For example,
if you source the following script:
vim9script
var time = reltime()
var attr: list<dict<any>>
for i: number in range(100'000)
attr = [{
name: 'ErrorMsg',
ctermfg: '253',
ctermbg: '168',
guibg: '#d75f87',
guifg: '#dadada',
term: {standout: true},
}]
endfor
(reltime(time)->reltimestr()->matchstr('.*\..\{,3}') .. ' seconds to run
the script')->setline(1)
The above script takes around 0.630 seconds in my setup (without any calls
to hlset()).
So it looks like most of the time is spent outside of the hlset() function.
