      Fixed a bug in the ndbd scheduler with send of packed signals. · 0a507d2c
      unknown authored
      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:
