(or PGSQL) How about SMP support, especially considering the near future of computing with multi-core CPUs. Python people consider this solved by adding processes, which may work ok for logic... I know MSSQL does take advantage of multiple CPUs and assume PGSQL is similar. I am guessing Metakit does not. Am I right? If so, will that ever change? Under what set of conditions? Ironically enough, the multi-process solution still depends on data storage, often via a memory mapped file, to provide safe and efficient data sharing/communication between processes. That may be ironic because Metakit is more similar to these memory mapped sharing techniques than MSSQL/PGSQL which DO provide good support for SMP. Will we simply assume people will "never need more than one cpu" for desktop applications and leave it at that? I should probably note that when doing heavy work in MSSQL, I still have idle CPU cycles. However, the same is not true of MetaKit doing the same work and this is on about the fastest x86 single-core hardware around, 2.5Ghz Athlon 64 (San Diego). I have DDR500 RAM and 10k RPM hard drives. So, the CPU is already the bottleneck for Metakit in my tests. Couple this with the likely fact that single-cores may actually get slower for a while as they are made to share space with other cores on a die, and it seems MetaKit performance may be limited for a while... This is a secondary consideration to my first concerning integrity. I just wanted to make note of it... I understand it's a big deal for many pieces of software, but I don't think it's too early to start supporting or at least considering multi-core CPUs. After all, I already left a multi-core machine for a faster single-core to stave off any performance limitations in the multi-core dilemma for at least a couple years. -- kai _____________________________________________ Metakit mailing list - [email protected] http://www.equi4.com/mailman/listinfo/metakit
