------- Comment #17 from paolo dot carlini at oracle dot com 2010-09-09 10:42 ------- At some point I tried quickly replacing some getc, did notice an improvement of course, but of the order of magnitude I mentioned. Worth further investigating sure (and simple, just replace in stdio_sync_ and measure, on Linux). In terms of the C++ Standard, I think that C++98 would allow essentially *anything*, not so C++0x, and within C++98 too I'm afraid we can break code making already some assumptions about the thread safety, which we don't spell out anywhere as impl def behavior, still...
