I currently have the MaxVirtualHosts set to 30000, and I haven't
encountered any sort of performance issues. My take would be to just for
for it, set it to something that gives you a comfortable cushion above your
current usage (if 4200 requires you to keep deleting unused hosts, try
setting it to 7000 perhaps?). If for whatever reason it causes issues, it's
very simple to set it back to 4200.
