Re: vim9 Benchmark

But there might other things that come into play. In neovim setline() seems to be much faster (when it's setting multiple lines).

For example:

======================================================

neovim lua

======================================================

local getlines = vim.api.nvim_buf_get_lines
local setlines = vim.api.nvim_buf_set_lines
local exec = vim.cmd

function LuaTest()
  local totallen = 0
  local start = vim.fn.reltime()
  exec 'new'
  exec 'call setline(1, range(100000))'
  exec ('echom "After setting lines to range: "' .. vim.fn.reltimestr(vim.fn.reltime(start)))
  local bnr = vim.fn.bufnr()
  local lines = getlines(bnr, 0, -1, false)
  for i = 1, 100000 do
    lines[i] = '    ' .. lines[i]
    totallen = totallen + lines[i]:len()
  end
  setlines(bnr, 0, -1, false, lines)
  exec ('echom ' .. totallen)
  exec ('echom ' .. vim.fn.reltimestr(vim.fn.reltime(start)))
  exec 'bwipe!'
end

======================================================

Result:

After setting lines to range:  0.062205
888890
0.200782

======================================================

gVim 8.2

======================================================

vim9script

def VimTest1(): void
    echom 'VimTest1'
    var totallen = 0
    var start = reltime()
    new
    setline(1, range(100000))
    echom 'After setting lines to range: ' .. reltimestr(reltime(start))
    for i in range(1, 100000)
        setline(i, '    ' .. getline(i))
        totallen += len(getline(i))
    endfor
    echom totallen
    echom 'After processing loop: ' .. reltimestr(reltime(start))
    bwipe!
enddef

def VimTest2(): void
    echom 'VimTest2'
    var totallen = 0
    var start = reltime()
    new
    setline(1, range(100000))
    echom 'After setting lines to range: ' .. reltimestr(reltime(start))
    var lines = getline(1, 100000)
    for i in range(100000)
        lines[i] = '    ' .. lines[i]
        totallen += len(lines[i])
    endfor
    echom 'After processing loop: ' .. reltimestr(reltime(start))
    setline(1, lines)
    echom 'After setting modified lines: ' .. reltimestr(reltime(start))
    echom totallen
    echom reltimestr(reltime(start))
    bwipe!
enddef

def g:VimTests(): void
    VimTest1()
    VimTest2()
enddef

======================================================

Result:

VimTest1

After setting lines to range:   0.110934

I repeated those tests multiple times. It seems to be a bit slower, yes.

That is even slower?
