With some compiler tuning and a few tricks (two changes to the code and hand-simulated peephole optimizations, but I think these tricks can also the compiler do): florian@ubuntu32:~$ ./vipribench VipriBenchThreaded - RunningTimeSeconds=5, TestCount=100, StartSeq=0, NumberOfChannels=6, BufferPackets=5000, NumberOfSynchroThreads=4 ..............................................................................................
