I have recently watched Larry Hastings talk about Removing Python's GIL: The Gilectomy that has been recorded at PyCon 2016. Larry very graphically outlines the problems from not having proper concurrency features. He also tells a nice story on how the Python community is struggling with this situation for the last 24 years.

If I am about to implement something it usually turns out to be a good idea to first start with some prototypes & benchmarks. This post summarizes the outcome of such an experiment to read data from compressed tar archives effectively. I did some similar benchmarks about 30 month ago so I repeated the measurements to see if there have been improvements and added results for my new Go reader.

Website hosting has changed dramatically over the last 20 years. I personally took part in this journey as a webmaster of a (recently) successful media site. In this article I summarize my journey and give a report on the technology I am using now.
