Lsp is too slow with blink.cmp

[ask-786]

Am i doing anything wrong here?

my lsp is just too slow with this configuration. not just completion, the whole lsp get's slowed down by this. like hover, jump to definition etc..

note:- . but it's working just fine with nvim.cmp

lsp configuration :-

M.capabilities = function()
	return require('blink.cmp').get_lsp_capabilities({
		textDocument = {
			foldingRange = {
				dynamicRegistration = false,
				lineFoldingOnly = true,
			},
		},
	})
end

M.lsp_config = function()
	local lsp_config = require('lspconfig')
	local mason_lsp_config = require('mason-lspconfig')

	local original_open_floating_preview = vim.lsp.util.open_floating_preview

	---@diagnostic disable-next-line: duplicate-set-field
	function vim.lsp.util.open_floating_preview(contents, syntax, opts, ...)
		opts = opts or {}
		opts.border = opts.border or 'rounded'
		return original_open_floating_preview(contents, syntax, opts, ...)
	end

	mason_lsp_config.setup({
		automatic_installation = false,
		ensure_installed = { 'ts_ls', 'lua_ls' },

		handlers = {
			function(server_name)
				local server = lsp_config[server_name] or {}
				server.on_attach = M.on_attach
				server.capabilities = M.capabilities()
				lsp_config[server_name].setup(server)
			end,
			ts_ls = noop,
			angularls = noop,
		},
	})

	lsp_config.dartls.setup({
		on_attach = M.on_attach,
		capabilities = M.capabilities(),
	})

	lsp_config.angularls.setup({
		on_attach = M.on_attach,
		capabilities = M.capabilities(),
		settings = {
			angular = { forceStrictTemplates = true },
		},
	})
end

blink configuration :-
