Gili Kamma :: Lessons I learn from improving legacy product and doubling its performance
Presented at Core C++ 2023 conference in Tel Aviv.
On 2017, I worked on an embedded central unit (linux, c++, QT) that was supposed to listens to many endpoints and pass their rf frames to the Server. Sometimes we had unexplained resets and sometimes we lost data(frames). I emphasize sometimes because most of the time everything worked well. This made it harder to find and simulate the problems. The central unit was supposed to support 7500 endpoints but in the real world after 5000 endpoints it crashed occasionally. Customers complained, the software was hard to maintain and very unpopular (for the developers) to work on. After two years of work, the unit supported 10k endpoints without resets or any loss of data. Let me tell you, how we did it.
