It takes 10+ seconds for an HTTP request from my Droplet to another server to complete. I can confirm that it’s not an issue with poor application code, but something deeper at the networking level. Just running basic curl and outputting timings produces:
$ curl -w "@curl-timings" -o /dev/null -s google.com time_namelookup: 10.044 time_connect: 10.045 time_appconnect: 0.000 time_pretransfer: 10.045 time_redirect: 0.000 time_starttransfer: 10.065 ---------- time_total: 10.065
But as soon as you replace the domain name:
$ curl -w "@curl-timings" -o /dev/null -s 220.127.116.11 time_namelookup: 0.000 time_connect: 0.001 time_appconnect: 0.000 time_pretransfer: 0.001 time_redirect: 0.000 time_starttransfer: 0.039 ---------- time_total: 0.039
This smells like something to do with how my Droplet is performing DNS lookup/resolution, but I don’t really know where to start looking or what to poke around at. Any help?
