I created a new dir /var/local/afprod2/tmp, mounted tmpfs with $ mount -t tmpfs -o mode=1777,size=222M none /var/local/afprod2/tmp and startet the guest with HOME=/var/local/afprod2 TMPDIR=/var/local/afprod2/tmp linux ... But I don't measure any performance increase. Do I miss something? Do I need a special kernel?

Check this: How can double caching cause blocking IO? Isn't it just a little waste of memory?
