Well, most other things don't create "shared-nothing" environments like PHP does. ASP, not only due to the Application object, for instance isn't shared-nothing like PHP but sharing state. So what we're doing, basically, is emulate a separation of threads, similar to what an operating system should do with processes. Of course an opcode cache isn't shred-nothing either, and maybe sharing opcodes within a process is faster than doing this in shared memory. > > Miss the rest of my mail or? Current implementation is outdated and > slow. That is true. Many modern compilers and environments provide better support for thread local storages .... What I see is that TSRM brings a lot of complexity and introduces risk of bugs in there as many developers don't think about. Most of us are focused on the nice and simple world of single-threaded computing. And I assume that we can still find quite some threading bugs when going on a hunt for them ... so besides of pure executable performance there is also the cost of developer power for (proper) maintenance ... johannes
