+# Openresty (Nginx + Lua(jit) Benchmark Test
+
+The lua app is inside [app.lua](app.lua)
+The nginx conf is inside [nginx.conf](nginx.conf)
+Requires a nginx compiled with ngx_lua module, see [openresty.org](http://openresty.org)
+
+Requires mysql hostname specified as IP address, if not possible then add resolver conf to nginx.conf.
+
+
+## Test URLs
+### JSON Encoding 
+
+http://localhost:8080/json
+
+### Single Row Random Query
+
+http://localhost:8080/db
+
+### Variable Row Query Test
+
+http://localhost:8080/db?queries=2
