Neotest introduces a lot of lag when not testing

[schester44]

Let me know if there is more I can provide here but i'm seeing severe lag / freezing (entire neovim program freezes) when browsing files after testing with neotest. I'm using the basic run test file and run nearest test commands. I've attached my config below and a screenshot from a profiler. Is this expected or am I doing something wrong?

Config

return {
  'nvim-neotest/neotest',
  dependencies = {
    'nvim-neotest/nvim-nio',
    'nvim-lua/plenary.nvim',

    'nvim-treesitter/nvim-treesitter',
    'marilari88/neotest-vitest',
    'adrigzr/neotest-mocha',
  },
  config = function()
    -- Keymaps
