Hello guys! I’m working on an asynchronous implementation of filter, but it never finishes. The code below is for testing a list of 950 proxies to see which ones are still working and if the response time was less than 5 seconds. It works fine for up to 200 proxies, but for the 950 it never runs out. Any hints as to what it could be? Is there any way to optimize this?
```julia
const conf = (readtimeout=5, retry=false)
url = "https://api.ipify.org/?format=json"
proxies = CSV.File("proxies.csv") |> Tables.matrix |> vec
function test(proxy)
resp = ""
try
resp = HTTP.get(url, proxy="http://$proxy"; conf...).body |> String |> JSON.Parser.parse |> x -> x["ip"]
catch
end
if resp != ""
println(threadid(), " ok ", proxy)
return true
else
println(threadid(), " fail ", proxy)
return false
end
end
function asyncfilter(f, i)
if length(i) >= 2
head = i[1]
tail = i[2:end]
fun = @async f(head)
recursion = @async asyncfilter(f, tail)
if fetch(@sync fun)
return [head, fetch(@sync recursion)...]
else
return [fetch(@sync recursion)...]
end
else
return i
end
end
result = asyncfilter(test, proxies)
```

I don’t think that’s how `@sync` works. It has to enclose the `@async` calls syntactically to wait on them. `fetch` also already blocks & waits on the return value of the task, so the `@sync` is superfluous.
That aside, this will be VERY inefficient, due to creating lots and lots of intermediary arrays and splatting them, as well as creating a copy on slicing and more tasks than necessary due to the recursion - it’s probably better to just `asyncmap` your test function.

The problem continues in asyncmap.

It’s not really possible to further help debug this without your `proxies.csv` file - what code exactly are you running with `asyncmap`? The same `test` function?

> what code exactly are you running with `asyncmap`? The same `test` function?
yes
```julia
result = asyncmap(test, proxies)
```
