You can see two sleep 1s, and finally use only 1.00099211s. Indicates that the co-process is concurrent.
Some performance metrics. Go to the HTTP call back end, on i7-6700k, with Ab-n 100-c 4 can run out of such results
Requests per second: 3183.70 [#/sec] (mean) time per request: 1.256 [MS] (mean) time per request: 0.314 [MS] ( Mean, across all concurrent requests)
If you do not use the HTTP call back end, direct php=>go return "Hello", you can achieve
Requests per second:10073.54 [#/sec] (mean) time per request:0.397 [MS] (mean) time per request:0.099 [MS] (MEA N, across all concurrent requests)
These metrics only illustrate the cost of the co-process switchover. The actual gain depends on the latency of the backend HTTP service, and if it takes a long time, the benefits can be significant through concurrent concurrency.
This experiment shows that an application server can be implemented with Golang instead of NGINX+PHP-FPM. It also provides a smooth migration path from PHP to Golang. Mix PHP and go in one app in two languages.
I/O can also be asynchronous by providing the Golang function to the PHP call. Extensions like Libcurl support asynchronous callbacks, except that PHP is synchronous, so only the synchronous execute is exposed to PHP. With Golang, execute can be transformed into an asynchronous execute+callback wrapper, enabling scheduling based on the co-scheduling.
