A question about Connection Reuse in Ice
in Help Center
Ice manual says:
This is Ice's only choice! Maybe Ice should add an additional config property to allow every proxy use a new connection!
the Ice run time will open a new connection only if it cannot reuse an existing connection to any of the endpoints.

Why would you want to do this? This would be expensive on the client-side. On the server side it could be quite fatal assuming a number of clients who each want to open up a large number of connections.

I think that "per connection per proxy on the client side " maybe have better performance when much data should be transfered between client and server.
Other advantages may exist also...0 -
Another question:)
1.First we get a proxy:
Ice::CommunicatorPtr ic = Ice::initialize(argc, argv);
Ice::ObjectPrx base = ic->stringToProxy(
"SimplePrinter:default -p 10000");
PrinterPrx printer = PrinterPrx::checkedCast(base);
2.Then we start two or more threads which call this proxy's operations without lock control
thread1()
{
for (int i=0; i<100; i++)
printer->printString();
}
thread2()
{
for (int i=0; i<100; i++)
printer->printString();
}
Is there any problem? Is the above code thread-safe ?0 -
Yes, the above is thread safe. All operations on a proxy (or on any other Ice objects for that matter) are thread safe.
Using more than one TCP connection won't give you a higher transfer speed. The speed is limited by the overall physical connection speed, like 100 mbit/sec on fast Ethernet, 1.5 mbit/sec on a T1 line, etc. It doesn't matter how many logical connections (i.e., TCP connections) you open.0 -
Thank you, I understand
