Thanks Robert. I appreciate it and also want to apologize if I sounded too harsh. I value the effort you put into the serialization library and just want to make it usable for high-performance applications as well.
Just to add another use case : Back in 2001 (or so), I had to implement serialization for IPC involving message passing between C++ programs on a RTOS (QNX) - the message passing was built on shared memory and QNX pulses (v. fast), QNX message passing (fast) and posix message queues (medium). Since I was using C++, I had a look at an early version of the serialization library (in the yahoo boost files section). It was way too slow, since I needed to pass serialized message objects that contained arrays of hundreds of POD elements between processes, and I was doing this hundreds of times a second. I ended up implementing (from scratch) something quite similar to the early serialization library, but which had a traits hook for optimizing array serialization (and lots of other differences - I forget). I achieved the necessary speed increase; it made the difference between a system that could handle thousands of digital IO changes per second, and one that could handle hundreds. Tom
