http://issues.apache.org/bugzilla/show_bug.cgi?id=30259 When proxy connects to backend, a DNS lookup is done every time. Investigate a DNS cache Summary: When proxy connects to backend, a DNS lookup is done every time. Investigate a DNS cache Product: Apache httpd-2.0 Version: 2.0-HEAD Platform: Other OS/Version: Other Status: NEW Severity: Enhancement Priority: Other Component: mod_proxy AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] When proxy_http (and I assume the other proxy modules) make a connection to the backend, a DNS lookup is potentially performed for each request. A simple DNS cache, flushed on server graceful restart, should improve performance here. To make this configurable, a timeout should be set as to the age of the entires in the cache, 0 meaning "don't cache". A typical value might be 1 minute or so - short enough so that admins who change the IP in DNS and then don't see the change in their httpd installation won't be sent on a wild goose chase, but long enough to make a significant difference to performance. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
