<< Is EDB going to be multi-threaded to gain maximum performance on multi-core CPUs ? >> I'm going to answer a question with a question: how could you possibly be using ElevateDB all these years and *not* know the answer to that question ? ![]() Yes, of course it can use multi-core CPUs, just like any other process that creates multiple threads and doesn't specify any processor affinity. In such a case the OS will schedule the execution of the threads as necessary on each CPU/core. Tim Young Elevate Software www.elevatesoft.com |

And unlike Microsoft and Oracle, you don't have to pay more for the EDB Server if you are using more CPU's. Barry (Gee, I hope I didn't give Tim any ideas <vbg>) |

Eg, Select, JOINs etc using local engine not the EDB Server |

Sure if you had a monster machine with 32 processors, parallel operations would make better use of the processors that otherwise might be underutilized. But on a busy EDB server with 4 processors, the other 3 processors would be handling other queries. So from my reasoning, if you used 3 or 4 processors in parallel to handle one query on a machine with only 4 processors, the other queries would back up. So unless you had a lot of processors, parallel operations probably won't make much speed difference. You'd be far better off cramming as much RAM as possible into the machine. Just my 2 cents.
