Intermittent pauses in connection

• Julia 1.8

Set-up here, copied out julia code below

I'm getting fairly frequent 300ms+ pauses on requests, setting up the connection

In a real, heavier application these pauses are occurring more frequently. Tested on both Windows and WSL

using HTTP, JSON3, Sockets, Tables

const router = HTTP.Router()

function middleware(handler)
	return function(req::HTTP.Request)
		ret = handler(req)
		if ret isa HTTP.Response
			return ret
		end
		return HTTP.Response(200, JSON3.write(ret))
	end
end

function index(req::HTTP.Request)
	home = read("index.html")
	return HTTP.Response(200, home)
end
HTTP.register!(router, "GET", "/", index)

const data = Tables.rowtable((; a=rand(100), b=rand(100), c=rand(100)))

function api(req::HTTP.Request)
	return data
end
HTTP.register!(router, "GET", "/api/test", api)

HTTP.serve(router |> middleware, Sockets.localhost, 8033)

Not able to reproduce this reliably on a different windows machine - might have just been constrained memory on the other box making more GC pauses? Closing for now.
