i know about the limits in the conf file, mine dont have limits there, was wondering why i cant get better than 80mbits/sec luezman> limits there, was wondering why i cant get better than Bluezman> 80mbits/sec
How fast is your WAN, and what is the RTT time from Ping across it? Basically, snapvault/snapmirror sucks for WAN work, no matter what NetApp says.
But I also agree it's a hard problem which TCP isn't really setup to handle well due to it's Window Size defaults. Even with Snapmirror setup to a 2mb window size by default, which should be enough for my WAN link, I can still see the data transfer being a sawtooth, instead of a smoother line.
