3. sometimes it become hard to browse , but it going normal after i
disabled all SIBLING, if i enabled it will slow again.
my file descriptor already 65535
my peer config
# cache_peer 10.10.10.10 sibling 3128 3130 no-netdb-exchange no-digest
no-delay round-robin proxy-only
cache_peer 10.10.10.11 sibling 3128 3130 no-netdb-exchange no-digest
no-delay round-robin proxy-only
cache_peer 10.10.10.12 sibling 3128 3130 no-netdb-exchange no-digest
no-delay round-robin proxy-only
cache_peer 10.10.10.13 sibling 3128 3130 no-netdb-exchange no-digest
no-delay round-robin proxy-only
any suggestion what best configuration for sibling peer ?
I don't think that round-robin makes much sense with sibling selection.
Either the a sibling has the object (and we grab the object from it) or
it doesn't (and we grab the object directly).
For myself, I use a line like...
cache_peer proxypool-2.my.domain sibling 8080 3130 no-digest
