is socket.http slow?

I'm executing a simple GET with socket.http to my local api (json-server) and it's taking about 2 seconds to finish the request.
Is this normal?
Code: Select all
local conn = require 'socket.http'
print(os.time())
local r, s = conn.request(url)
print(os.time())
the above code produces:
When i call the api from the browser the request returns almost instantly.

I get a pretty stable 334 ms when querying
http://example.com. By the way, socket includes a gettime() function with sub-second precision:
Code: Select all
local url = 'http://example.com'
local gettime = require 'socket'.gettime
local conn = require 'socket.http'
local start = gettime()
local r, s = conn.request(url)
print(gettime() - start)
Not sure what the cause may be in your case. Perhaps your browser has cached the result and that's why it seems to respond much quickly.

Well i should have tested it with another api before opening the thread, your example runs pretty fast in my machine too. I think the problem is json-server, for some reason it is slow when called from socket.http.
