My Mac OS X (10.6 & 10.7) clients all intermittently but frequently experience extremely slow connection times to my Windows 2008R2 shares. From the Go To Server menu, they can enter an smb:// path either in FQDN or IP and connect, but encounter a delay up to 20 minutes or more. Once the share is mounted, performance is fine. I remain baffled.
Things I've tried:
- disabling mDNS broadcast
- Setting IPv6 to inactive
- changing the mdns_timeout to 1 and 0
- setting the TCP delayed ACK to 0
Thanks to all!
