i communicating parallel processes using fifos. reading pipe read(). , writing named pipe doing this:
ofstream pipe(namepipe); pipe << data << endl; pipe.close(); i have been noticing performance horrible though! takes 40ms sometimes. it's extreme latency in opinion. read use of std::endl can affect performance. should avoid using endl?
does using ofstream affect performance? there other alternatives method?
thank you!
a cheap hack:
std::ios::sync_with_stdio(false); note use if not going mixing c io c++
the reason std::endl might affect i/o performance because flushes stream. avoid this, should use '\n'
avoiding having open , close multiple streams help
