Thanks for the report but this was to be expected as the change was related to DHCP only. Which guest are you using? Which host machine are you using? Do you have VT-x enabled (make sure you have not). Do you have USB enabled? Try switching this off at it costs performance as well. Furthermore, you could also build a profile build. Edit the env.sh file manually and replace BUILD_TYPE="release" by BUILD_TYPE="profile". Recompile (there will be a new directory out/*/profile/... . When you start the GUI you will note a new menu entry 'Debug' which contains the entry 'Statistics...'. Open this window and you will see a bunch of counters. Go to Devices/PCNet0. Then Increase the update interval from 0s to 1s. Re-arrange the columns with the mouse, move the dInt (which is IMHO the most important column) more to the left. Then start your networking benchmark. During boot you might experience some delays resulting from initializing the counters. No worry about that. During the benchmark have a look at the UpdateIRQ rate and updates in the XmitFlushIRQ array. The latter should show frequent changes in all members. The more changes in 12-16 the better (that means that bunches of packets are sent). Perhaps you will only see updates for XmitFlushIrq=1 ... Kind regards, Frank -- Dr.-Ing.
