In parallel concurrency as you a business transactions are completed per second users per minute. For instance, with a three second caching tolerance, the back end need only make 20 calculations per minute, regardless of how many API requests are handled. If a module doesn't pass generated requests through this code, the author is cautioned that the module may be broken by future changes to request processing. If your 50th percentile response time is 100ms, that means 50% of the requests were returned in 100ms or less. -rate=2000 The number of requests per second. At higher levels of concurrency, it can handle fewer requests per second, but still more than Apache. If the handler is changed to time.sleep(0.5), i.e if each request could respond in approximately 0.5 seconds then server would be able to handle 20 requests per second. .

All requests pass through ap_process_request_internal () in server/request.c, including subrequests and redirects. The architecture must remain intact. Requests per second is the average of how many requests the web server was able to handle in a second. In our example, Apache instantiated 49 workers (only 27 busy workers, 22 idle workers). When the number of simultaneous HTTP requests exceeds this count, the unhandled requests are placed in a queue, and the requests in this queue are serviced as processing threads become available. Apache is the venerable old-timer in the http server world. With 2 nodes and 2 shards we got 43k events . Although it has not been designed specifically to set benchmark records, Apache 2.x is capable of high performance in many real-world situations. Server Performance metric How many requests per second. We can also see that the number of requests per second was a lot higher with event MPM which means it can handle more simultaneous users. 70 requests per second works out to an hourly rate of 252,000 page renders / hour. How many calculations can a i7 do per second? Funny thing is that limux/apache have solved c10K problem more than 10 years ago yet apache on windows still can't handle it.
