Recently I’ve refurbished an old project of mine, the Call Center Simulator CCsim (https://apps.apple.com/de/app/ccsim/id1519438028?mt=12). It was a lot of fun to develop this heavy multithreading app. One main reason for me at the very beginning was to see how big the influence of the actual shape of distributions (e.g. for the call duration) besides the mean value is on the results. Now we do have this tool and we can play around a little bit.

Performance of a Heavy Multithreading App on Apple Silicon
I couldn’t resist. Now, the new Apple Silicon macs are out and I had to buy a new Mac mini to test my applications on the new architecture (and the new macOS 11.0). Recently I released my refurbished project, the call center simulator CCsim (https://apps.apple.com/de/app/ccsim/id1519438028?mt=12). It is heavily relying on multithreading and I was eager to see what it is doing on M1-equipped macs. Weiterlesen
Performance of Swift vs. Objective-C and the Debugger
Recently I have migrated an old project of mine from Objective-C to Swift. It was not that difficult and it worked out fine, and I was eager to see how the performance of the migrated system would turn out. How big was my disappointment when I saw that the Swift version of my system was at least a factor of 10 slower than the Objective-C version with unchanged functionality. That can’t be true, I thought and debugged at little bit.
