Just notice the difference between python2 and python3 simple http server $ python -m SimpleHTTPServer 8000 $ python3 -m http.server 8000 Even the python3 is nicer to read, I really like that they package the server in a module. It's almost twice as slower in my machine. Python2 Benchmark Requests per second: 606.03 [#/sec] (mean) Time per request: 8.250 [ms] (mean) Time per request: 1.650 [ms] (mean, across all concurrent requests) Transfer rate: 4412.05 [Kbytes/sec] received And Python3 Benchmark Requests per second: 412.51 [#/sec] (mean) Time per request: 12.121 [ms] (mean) Time per request: 2.424 [ms] (mean, across all concurrent requests) Transfer rate: 3003.17 [Kbytes/sec] received Both 1000 requests, concurrency level of 5. Listing a large directory with thousands of files. I usually use python simple http server to share files and provide synchronization. One hopes that with a new python release it will get faster or at least smarter, both are the same implementation with no noticeable difference, just that python3 is slower.
