Dear Rooters Maybe this is a good opportunity to ask some questions about TThread: 1, In which cases would it be recommended to use class TThread? 2, Support for Dual-Processor machines: Sorrowly, I do not have such a machine :-(, but for interest: If you write programs in root and want your program to take advantage of a dual-processor machine: What is the best way to achieve this goal? Do you need to use PROOF? Would TThread support dual-processors? As far as I understand, Mach (MacOSX) threads support SMP. Does root TThread support this? What about Linux? Does not WinNT also support threads? 3, The tutorial spyserver.C shows how a TServerSocket can handle requests from two or more clients. No threads are necessary. In which cases would threads be necessary? Could this tutorial be expanded to show how to use TThreads? Thank you.
