!! Performance
I wanted to get an idea of much overhead there is, so comparing running a load on native hardware against running under VirtualBox.\\
Now you do a complete study on this subject, but no time for that.
I did just one very simple test :
{{{
metskem@ubm7:/tmp$ time tar -czf /tmp/ff.tar /usr/*
tar: Removing leading `/' from member names
tar: Removing leading `/' from hard link targets
real 1m20.259s
user 0m27.586s
sys 0m27.286s
}}}
Then scp this tar file to the host, untar it to a temp directory and tar it again in the same way :
{{{
metskem@gneisenau /tmp/fff $ time tar -czf /tmp/ffnative.tar usr
real 0m29.273s
user 0m26.282s
sys 0m1.284s
}}}
||type||host ||guest
|real|29|80
|user|26|28
|sys|1|27
This is rather disappointing, I like to do some testing with a Java workload....
