I've never tried, but my guess is that they will both try to cache
every file.  In other words, this is not a good idea.

You've already heard the opinions on this.  In general, disk_cache is
better tested and will perform better with large cache sets.  Its
performance depends mostly on the efficiency of your OS buffer caches.

Is CacheRoot writable by the httpd User/Group?  Try turning LogLevel
to debug and running a cachable request.
