Hi all, I did a first perfomance test extending the demo example by tracing 30 simple integers in a loop.
For a similar CPU (i5 quad core 2.8GHz) I saw values mentioned around 250ns in the forum. I've tried the test several time and could come down to about 350ns. The machine was almost idle for all tests. What makes me wonder is a large variation with frequent runs giving me 750-800ns. Not the absolute time but the variations isn't clear to me. From my understanding the caller path is more or less straight to shared memory. Why do different runs show more than double the time for the traces?
