Evrone at Highload++ 2021: stands, games, magic
Highload is the largest professional IT conference for developers of high-load systems. It has been held since 2007, and during this time more than 22,000 people have taken part in it.
We've been presenting at and attending conferences for years, and we became Highload partners back in 2020. However, due to the pandemic, some of the events that year were canceled, and some were moved online. But in 2021, we participated in full. We showed films about ourselves at the stand and gave a presentation in the main hall.
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.
