Evrone at TeamLeadConf 2021 and the Highload ++ conferences
TeamLeadConf took place earlier than Highload and was one of the first conferences to go offline. Therefore, there were few participants with stands. Nevertheless, the visitors were not bored - the organizers provided activities during all breaks.
Unlike narrow-profile conferences devoted to specific languages or issues, TeamLeadConf is universal. There you can meet developers, managers, DevOps, and QA specialists who want to learn more about technical management.
On April 29–30, 2021, the TeamLeadConf was held at the World Trade Center in Moscow. Evrone was there with a stand for participants, and team members Tatiana Sukhodolova and Mikhail Grachev presented their reports.
What is the report about?
In short: It is generally accepted that Python and Ruby projects are not designed for heavy workloads, but this is not always the case. Python and Ruby are really slow and with the GIL, when used correctly, this is not a problem, but an expense.
A little less briefly: When an easy way to scale service under load disappears, a high-load appears. But many services have been running on non-high-load PHP, Python, and Ruby for years, processing thousands of web requests per second, without the need to write their own PHP compiler or switch to Go from Rust. Grigory explained when exactly the turning point for Python and Ruby comes. Using examples of typical Python and Ruby projects, he showed what exactly happens after nginx, how modern application servers for these languages interact with virtual machines, what web frameworks give and take away, and how all this differs in speed from the "C high-load", capable of issuing hundreds of thousands of requests per second.
