Thanks. I checked the 1.3.0 but there was no ARM build. Did not 
realize there is one for 1.1.0.

For anybody finding this using google search, simply do the 
following to install:

My code now works correctly again. Doing some benchmarks 
Apache+PHP vs Go vs D on the Raspberry Pi 3.

n=100000 c=500

Apache: 1488 seconds
Requests per second: 67.20

Go+Gin: 123 seconds
Requests per second: 812.23

D: 149 seconds
Requests per second: 629.46

D is running a simple socket + limited HTTP 1.0/REST framework 
that i gobbled together. No optimizations. Go is running a 
complete HTTP/REST framework so it has more overhead.
Apache+PHP5.6 simply suffer beyond belief.

Take in account, the D has only been done on a single core! Where 
all the others used all 4 cores.

Impressive even if its not apples to apples comparison.
