As smuxi [0] uses .NET remoting very heavily I had to test/tune a lot...
I found object references are very expensive, and not all objects need
to be passed by reference, like simple data containers (models). Just
add the Serializable attribute to those classes instead of extending
MarshalByRefObject.
Also synchronized calls are (time-)expensive, you should either try to
reduce the number of calls or use async calls.
I often use ngrep (network sniffer) to find unneeded calls, as the whole
communication is very transparent, you easily do calls without
knowing/noticing it....
