...amdahls law. Indeed. There is always a lot of serial stuff in any code. Whats worse is that the serial part has its 'working set' mostly cache-resident. Farming a chunk of work out to other threads first has to make up for the transfer of cached data to the other threads. This needs to happen before the other threads start to actually help, rather than impair, performance. Again the longer the cpujob is the less this transient behaviour hurts. Its why i would suggest vectorization first. It almost always helps.. Sent from my Android device with K-9 Mail.
