Hi,
The jumbo-frames in my case give me a boost of around 2 mb/s, so it's
not that much.
That is about right. IIRC, the theoretical max is about 4%
improvement, for MTU of 8KB.
Now i will play with link aggregation and see how it goes, and of
course i'm counting that incremental replication will be slower...but
since the amount of data would be much less probably it will still
deliver a good performance.
Probably won't help at all because of the brain dead way link
aggregation has to
work. See "Ordering of frames" at

Arse, thanks for reminding me Richard! A single stream will only use one
path in a LAG.
Doesn't (Open)Solaris have the option of setting the aggregate up as a
FEC or in roundrobin mode?
Not if a switch is used, data between a pair of endpoints (IP addresses
or address/port combination) uses one physical link. The same most
likely applies to direct connections given the IP stack doesn't know how
the ports are connected. I'd be interested to know how they do this if
I'm wrong!
