Hi mat, Actually it is not faster than any hand made protocol encoder - decoder, since it has the overhead of reflection. But most of the time the problem is not the encoding and decoding of streams, it is usually I/O or processing (not decoding or encoding) of messages that causes the performance problems. The aim of library is to make life easier if you have lots of different types of messages to encode and decode.
But it is fast enough for most applications. It can encode or decode more than 100.000 simple and small messages per second on an average box. You should try it yourself to see whether it is appropriate for your application. As for the endian problem, it also contains Little endian data streams for the job. There is also a mina example in the samples directory.. It is not complete, but gives an idea for use of javastruct for network protocols. Mehmet On 8/21/07, mat <[EMAIL PROTECTED]> wrote: > Thanks.
