The Using VoltDB manual has the following on P 62:

"Note that the C++ interface is single-threaded. The interface is not thread-safe and you should not use instances of the client, client response, or other client interface structures from within multiple concurrent threads."

Doesn't this severely impede performance? I already have a large amount of application code in C++ that I wish to convert to VoltDB, but I don't wish to run the entire app as single-threaded. Can anyone provide advice?
