The reason for adding ClamAV to the test-suite was more for testing
correctness than performance. (there were quite a few GCC bugs triggered
by ClamAV's code for example).
To do a proper performance test for ClamAV you need to run it for at
least half an hour on a large set of representative files, i.e. not
something for LLVM. Otherwise what might seem like a 20% improvement
could very well be just a 0.2% improvement in practice.
You can try to update to a newer version, I think the script that I used
to convert ClamAV's source-code to LLVM-test-suite-friendly source code
is still in the repository, although it may need updating as some new
files probably got added upstream.
Unfortunately I don't have the time to do this update myself at this time.
