well... the spike happens regardless which overview mechanism you're using. My 
experience is, from all the backends, OVDB needs the longest time to do an 
expire over the overview (around 6 hours on my system, it had around 12 GB 
overview back then with compression enabled on a 2.6 linux kernel, Athlon 
3200+, 1024 MB RAM).
