Synchronization performance varies with the JVM, processor, workload, JIT activity, number of processors, and the amount and character of code being executed using synchronization.

It defines dynamic strings, variants, character sets, lists and other basic data types along with portable thread and synchronization objects, IP sockets and named pipes.

A kind of offline clock synchronization algorithm is promoted based on the character of clock behavior and the cause and pattern of inaccuracy, with performance analysis provided.
