Re: Hitting rate limit?

Are you using keepalives?  If not, you're measuring mostly the TCP/SSL 
set up and teardown times.  Try ab -k.  I did some measurements recently 
on a web system and got 7 kreq/s for a non-SSL site without keepalives 
and 30kreq/s with.

If these curl commands are less than one second apart then you are 
unlikely to see any change in the DNS name resolution.  Try with a sleep 
2 in between.  Also, bear in mind that the DNS resolution is, according 
to the documentation, triggered by the health check.
