This project aims to create a tiny but functional application server by leveraging multithread and epoll features of linux OS.
All the source code is written in C. Please go to https://github.com/grassroot72/Maestro2 for better code structure
The project is a WIP (Work In Progress) project. It is still in its infant stage. More features will be added in the future.
- Multithread pool
- Epoll (so, linux specific)
- Non-blocking
- HTTP/1.1 GET method (static file)
- HTTP/1.1 HEAD method (static file)
- HTTP/1.1 POST method
- HTTP/1.1 chunked transfer
- HTTP/1.1 keep-alive (long connection, disconnected after timeouts)
- built-in cache to provide better GET performance
- deflate compression
- download resumption
git clone https://github.com/grassroot72/Maestro.git $ make ... $ ./maestro After you run the webserver, you should see the following
listening on port [9000]
then, you can open firefox or other browsers and key in the url http://localhost:9000 or http://localhost:9000/bench.html
To test download resumption, key in the following url in your browser(firefox), http://localhost:9000/download/Business-English-for-Success.pdf refresh the browser if download stalls. Keep refresh several times until the download finally finishes.
For Apache Bench, I used the following command, $ ab -k -n 500000 -c 1000 http://localhost:9000/bench.html You may also want to put the compression option on, $ ab -k -n 500000 -c 1000 -H "Accept-Encoding: deflate" http://localhost:9000/bench.html Please replace localhost with your hostname if you would like to test on other computers. The following is the test result on my very low-end laptop,
- CPU: Intel Celeron N2930 (4 cores) at ~2.16 GHz (2M Cache)
- MEM: 4G
- NET: laptop built-in wireless
This is ApacheBench, Version 2.3 <$Revision: 1879490 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking localhost (be patient) Completed 50000 requests Completed 100000 requests Completed 150000 requests Completed 200000 requests Completed 250000 requests Completed 300000 requests Completed 350000 requests Completed 400000 requests Completed 450000 requests Completed 500000 requests Finished 500000 requests Server Software: Maestro/1.0 Server Hostname: localhost Server Port: 9000 Document Path: /bench.html Document Length: 1025 bytes Concurrency Level: 1000 Time taken for tests: 34.448 seconds Complete requests: 500000 Failed requests: 0 Keep-Alive requests: 500000 Total transferred: 669500000 bytes HTML transferred: 512500000 bytes Requests per second: 14514.75 [#/sec] (mean) Time per request: 68.895 [ms] (mean) Time per request: 0.069 [ms] (mean, across all concurrent requests) Transfer rate: 18979.73 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 3.6 0 105 Processing: 27 69 18.4 65 178 Waiting: 5 43 13.6 45 137 Total: 27 69 18.7 65 181 Percentage of the requests served within a certain time (ms) 50% 65 66% 73 75% 79 80% 84 90% 96 95% 105 98% 115 99% 122 100% 181 (longest request) If you test it on most recently manufactured computers, you will get much better benchmark results. I am not the author of the pdf file under the download folder, I only use it for download resumption test.
I want to develop an HTTP/1.1 compatible webserver as well as an application server which skips traditional CGI function and directly provides dynamic services (POST) through built-in functions.
