Profiling application performance
By now, we have established that system programmers care about speed. Applications need to be as efficient and as fast as possible. But what if you think your application can go faster but do not know where or what to improve? That is where profiling and benchmarking can help.
Profiling is measuring and analyzing the performance of your application in terms of factors such as CPU usage, memory pressure, network performance, and so on. It’s like putting your app under a microscope. Things we look at during profiling are, amongst others, the following:
- CPU usage: Identify which parts of your application are using the most processing power
- Memory usage: Track how much memory is used and finding memory leaks or excessive allocations
- Function call frequency: See which methods are called the most and how long they take
- Performance hotspots: Pinpoint areas of code that are slower than they should be
