Fixing this bugs improves performance by 40% for very small read statements and with 12-13 % for very simple updating transactions (flexBench -o 10000) in single threaded application. Removes a fixed cost of around 100.000 cycles every time the ndbd process wakes up to execute some queries. ndb/src/kernel/vm/FastScheduler.cpp: Integrate sendPacked into doJob The lack of integration meant that several loops in ipControlLoop were executed each time the ndbd process woke up, also for reads it meant that response was divided in two TCP/IP packets Is necessary to integrate this with overload protection ndb/src/kernel/vm/ThreadConfig.cpp: Integrate sendPacked into doJob The lack of integration meant that several loops in ipControlLoop were executed each time the ndbd process woke up, also for reads it meant that response was divided in two TCP/IP packets Is necessary to integrate this with overload protection |
