Blocking Calls and dnsserver avg service

Hello,
two questions:
1. Why does squid report:

"Blocking calls to gethostbyname(): 4"

but on the other side

"dnsservers use histogram:
    dnsserver #1: 160
    dnsserver #2: 11
    dnsserver #3: 0
    dnsserver #4: 0
    dnsserver #5: 0
    dnsserver #6: 0
    dnsserver #7: 0
    dnsserver #8: 0
    dnsserver #9: 0
    dnsserver #10: 0"

2. Is a "dnsserver avg service time" of 2714 msec
normal for a good internet connection (2 MBit/s) ??
Should we even run a separate named on the squid machine ?

Background: We are experiencing strong delays for our customers in times
of heavy load. But where can I find out, if the delay is caused by our
parent squids, by our squid itself, or by slow hardware ...?

TIA
