[Ace-users] Need Suggestion for building a distributed platform based on ACE

[duke]

Hi
thanks for your comments.
It seems that TAO already has everything that i want.
my concern is that the performance of TAO.
our spec is pretty simple. just Linux+C++.
do not need to support other languages. but has large
volume of network transport in local network.
