Now, as we already know what kinds of tools can be used for profiling, there will come a time when we will have to get our hands dirty and delve deeper into typical performance optimization work. For you to be able to reproduce it, we have to agree on the exact versions of our frameworks and tools. To make it short, we've decided on the following:
- Qt 5.9 LTE
- Windows 10
- Open source tools
