I doubt if this is totally true. Upto Go version 1.4, the process would use only 1 core/cpu per process by default, but you could change it by: numCPU := runtime.NumCPU() ret := runtime.GOMAXPROCS(numCPU) From 1.5 the process the default value of MAXPROCS is total CPUs on the machine. So its not 'reduced parallelism compared to C/C++' rather the concurrency infrastructure (channels etc) makes it transparent to the programmer. I don't have to worry about creating a threadpool myself like C/C++ and Java. So overall there is a net gain, in my understanding. Am I wrong any where in this? |
