Description
Right now log record serialization is synchronized. We can improve concurrency by serializing to a ram buffer outside synchronization. The cost will be RAM usage for buffering, and more complex concurrency in the tlog itself (i.e. we must ensure that a close does not happen without flushing all in-RAM buffers)
