Speed up http post request

[pbelx]

My net.http code is taking 41 seconds to get reply. Here is the code below.What could be wrong?

import net.http

fn main(){
println("starting..")
posturl := "http://127.0.0.1:2222/billing/user_signin/"
post := '{"servedMSISDN": "2534444444","password": "dffdf4f7dd21d2293bd2d8500c507ad2c0414a156c6ea6f1d144bdc50cf244b82"}'
h:= http.new_header_from_map({http.CommonHeader.content_type:'application/json'})
println(h)
conf :=http.FetchConfig{
method:.post
url:posturl,
header:h,
data:post
user_agent:'volley-http'
}
resp := http.fetch(conf) !
println(resp.body)
}

Are you on Windows? There are so many things in Windows that can slow you down... anti-virus, Windows Defender, etc., etc.

Since you didn't supply your server code, there is no way for anyone else to test, but I would be willing to bet it takes milliseconds or less on Linux for the same code...

[pbelx]

Running on debian 10. Using curl command it takes around 9-10 seconds. But above code is always around 40-42 seconds.

[JalonSolov]

Are you certain your server code is responding fast enough?

You can try running with -d trace_http_request and -d trace_http_response to see what's happening.

You can also try using the benchmark module, and see if you can isolate the section(s) of code taking the most time.

[pbelx]

Have setup wireshark and can see that the json reply comes in earlier.
The delay is on the program printing the response.

[joe-conigliaro]

Also it would be good to see how you are running it, is compilation included in that time?

[pbelx]

compilation not included. running a binary file.

update using benchmark.

    import net.http
    import os
    import benchmark
    
    fn main(){
        println("starting..")
        mut b := benchmark.start()
        posturl := "http://127.0.0.1:2222/billing/user_signin/"
        post := '{"servedMSISDN": "252443434","password": "347f4f7dd21d2293bd2d8500c507ad2c0414a156c6ea6f1d144bdc50cf244b82"}'
    
    
        
        h:= http.new_header_from_map({http.CommonHeader.content_type:'application/json'})
        b.measure('create header')
    
        println(h)
        b.measure('print header')
        conf :=http.FetchConfig{
        method:.post
        url:posturl,
        header:h,
        data:post
        user_agent:'volley-http'
        }
        b.measure('create conf')
        resp := http.fetch(conf) !
        b.measure('use fetch')
        os.write_file("/tmp/js",resp.body) !
        b.measure('write body')
        println('done')

the results are.

[JalonSolov]

Now... can you add the same benchmarking code to your server? If it takes 36 seconds to do the fetch... is it because the server doesn't respond for 36 seconds?

[pbelx]

Server responds within 9 seconds..http chunked json. running curl like this.

time curl -X POST http://127.0.0.1:2222/billing/user_signin/ -H 'Content-Type: application/json' -d '{"servedMSISDN": "25222222","password": "3d7f4f5dd21d2293bd2d8500c507ad2c0414a156c6ea6f1d144bdc50cf244b82"}'

    real	0m12.481s
    user 0m0.004s
    sys	0m0.012s

The V client is consistent at 36 seconds using fetch
SPENT 0.010 ms in print header
SPENT 0.001 ms in create conf
SPENT 36071.013 ms in use fetch
SPENT 0.291 ms in write body

It would be ideal if you could setup a server/client script to demonstrate the issue.
Or at least provide the response from your server, my guess is this has something to do with chunking.
