Hi Since we are talking about improving SMTP data handler class I want to draw attention to some performance issues I had found earlier while analyzing CharTerminatedInputStream class.
The point of major concern was the use of read method to read data from Socket InputStream. for example if we consider an average mail size of 40KB, read method will be called 40 x 1024 = 40960 times and that consumes lot of CPU time. Number of calls can be easily reduced to just 20 if use block size of 2KB and that makes a huge difference of the overall throughput I have used PushBackInputStram and block read method to implement a mail proxy server for one of our client and the benchmark results were quite impressive against nonblock read method. In my case my server's mail handling capability increased two times. Sandi --- "Richard O.
