Slow copying and removing of the COW directory

What cowbuilder does is:

cp -al /var/cache/pbuilder/base.cow /tmp/new
rm -rf /tmp/new

Of course the location /tmp/new is something else. Try those commands and see how fast they are on your computer. You can compare them to our [:cowbuilder_benchmark: benchmarks].
