Premature optimization is evil!

I bring to your attention the first part of the translation of the book “Mature optimization” by Carlos Bueno on the principles of optimizing high-loaded projects.

The author of the book recently worked on Facebook and, as a member of the productivity team, he saved a lot of money for the company, using his meticulous measurement skills and thoughtful optimization. The author embodied all this experience in his book, and we brought it to you for free, in Russian and with illustrations.

The book is worth reading if you:

1. Want to improve the performance of your project, but do not know where to start .
2. You want to improve the performance of your project, but are afraid to break everything .
3. Do not know about the pitfalls of performance optimization .
4. I have long wanted to set up a project monitoring, but are not sure what exactly is worth monitoring .
5. You have a monitoring system, but it does not report problems in advance .



For this book, a small website was created, on which, over time, new chapters will appear.

I would be very happy to hear your impressions, as well as see likes and re-posts.
