  1. Hi all, I'm looking to find a decent, easy-to-use Profiler to help identify performance bottlenecks and memory leaks. I'm a small-project user so not looking to pay too much - free and open source options are welcome as long as they're straightforward to use - no command line stuff, please. It's 2023 and I'm using RAD Studio 10.4.2 - I believe SmartBear used to provide a standard version of AQTime with an earlier version of RAD, shame they stopped doing this really because now it seems we have to pay big bucks for this particular profiling system. Recommendations and suggestions welcome, thank you!
  2.

I haven't developed or amended any of the units mentioned in the report. I strongly doubt there is a leak in the units mentioned in the report as they are either part of the VCL or part of Indy but at the same time, I don't know where I can find the leak in my code. Can anybody help me? Many thanks Alberto
  3. I have started removing memory leaks in my application and installed and configured FastMM4. I ran the application and the following is an excerpt from the memory leaks report. --------------------------------2020/6/20 21:24:00-------------------------------- A memory block has been leaked.
