\nAccording to legend, there was a project whose product\nwas running too slow,\nso they spun off a subteam to see what architectural changes\nwould help them improve their performance.\nThe subteam returned some time later with a fork of the project\nthat they had “tuned”.\nAnd it was indeed the case that the performance-tuned version\nran a lot faster.\n<\/P>\n
\nLater, the development team discovered that part of the “tuning”\ninvolved simply deleting all the synchronization.\nThey didn’t replace it with lock-free algorithms\nor anything that clever.\nThey just removed all the critical sections.\n<\/P><\/p>\n","protected":false},"excerpt":{"rendered":"
