Question

I am making a call to a method by passing ipAddress and it will return back the location of ipAddress like Country, City, etc etc. So I was trying to see how much time it is taking for each call. So I set the start_time before making call to method and end_time after making a call. So sometimes I get difference as 0. And resp contains the valid response.

long start_time = System.currentTimeMillis();
resp = GeoLocationService.getLocationIp(ipAddress);
long end_time = System.currentTimeMillis();
long difference = end_time-start_time;

So that means sometimes it is taking 0 ms to get the response back. Any suggestions will be appreciated.

Answer 1

Try this

long start_time = System.nanoTime();
resp = GeoLocationService.getLocationByIp(ipAddress);
long end_time = System.nanoTime();
double difference = (end_time - start_time) / 1e6;
