RE: Performance boost with Upgrade to dual processor ??
You can actually set SQL7 to run on a particular processor. I know for a fact that SQL 7 can take advantage multiple processors. You have to be careful though, I am not sure but you may have to get another license.

Re: Performance boost with Upgrade to dual processor ??
The answer is no the operating system determines the processor usage. When processor 1 is all used up, then the OS instructs the system to begin using both processors to carry the load.

RE: Performance boost with Upgrade to dual processor ??
Just a question. Where did you get that answer? I am asking because I have a Dell Poweredge dual PIII 1 gig server here. The reason I got it was to build a high end dev box/workstation on it. Now in reading game magazines, and stuff I was under the impression that as long as you were on windows 2000 that you were using both processors full time? I may be wrong but I would just like to see it somewhere.

No, sql performance and all programs as it pertains to cpu usage are determined by the OS.

That's wrong man, This is off of msdn: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnsql2k/htm l/megasrvs.asp Here is the piece that pertains: Symmetric Multiprocessors SMP gives vertical growth from small processors to MegaServers by adding more processors, disks, and peripherals to a single system. Beyond a certain point, this growth involves replacing existing equipment with a different system model Symmetric multiprocessing (SMP) grows a server by adding multiple processors to a single shared memory. The system grows by adding memory, disks, network interfaces, and processors. SMP is the most popular way to scale beyond a single processor. The SMP software model, often called the shared memory model, runs a single copy of the operating system with application processes running as if they were on a single processor system. SMP systems are relatively easy to program. They also leverage the benefits of industry-standard software and hardware components. Microsoft Windows 2000 and Microsoft SQL Server 2000 are designed to scale well on SMP systems. They can use up to 32 processors for some applications but the practical limits for general-purpose use today are: Eight processors 32 gigabytes of main memory 10 TB of protected storage (300 36-GB disk drives configured as 60 hardware RAID sets and 10 logical volumes) 50,000 active clients accessing a SQL Server through the IIS Web server or some transaction monitor These are the maximum sizes Microsoft has seen. Typical large servers are half this size or less. With time, Microsoft SQL Server, Windows 2000, and hardware technology will evolve to support even larger configurations.

RE: Performance boost with Upgrade to dual processor ??
Hah definitive answer: Definition and Overview Symmetric multiprocessing is a computer architecture that provides high performance by making multiple CPUs available to individual processes. Symmetric multiprocessing fits between uniprocessor and parallel-processor approaches and captures many of the advantages of each. Uniprocessor systems present application software developers with a simple, linear, processing model and a global view of memory. Parallel-processors can perform calculations much more quickly, but at the extreme high end can require extensive customization of compilers and applications. Symmetric multiprocessing allows multiple processors to work in parallel and still use a single operating system image, common memory, and disk I/O resources. link: http://www.nswc.navy.mil/cosip/nov97/osa1197-1.shtml Tim Heald ACP/CCFD Application Development www.schoollink.net -Original Message- From: Tim Heald [mailto:[EMAIL PROTECTED]] Sent: Wednesday, April 24, 2002 4:11 AM To: CF-Talk Subject: RE: Performance boost with Upgrade to dual processor ??

RE: Performance boost with Upgrade to dual processor ??
AFAIK, Both processors are used (obviously, as the actual board is designed to do this). It may not use the processor 100% and give you better performance (a common misconception that 2 processers give you 2x speed!), but for OS's which support multi-processors it does take advantage (Win2K, NT4 DPE). SQL Server has a multiprocessor version out of the box and DOES take advantage of both processors out of the box. A machine which only used a spare processor when chip A has maxed out is pointless inefficient, you may as well pack it full of RAM, SCSI throuhout to help it on its way... My desktop machine has dual-p and I am monitoring it now, and I can confirm that it using both chips when needed, and not as a fallover solution. Hope this helps!

RE: Performance boost with Upgrade to dual processor ??
Basically to make use of multiple processors the requirement for an application is that it break it's load apart into multiple threads. If CF runs as a single thread it can not take special advantage of a MP system (beyond the obvious fact that the OS may or may not place it's thread on a CPU different than most other currently running apps.) I think that in any case, the core CF Application Server will always run with more than one thread. You have one thread responsible for listening and directing requests to worker threads, and you have N worker threads, N being the number specified in the simultaneous requests setting in CF Administrator. So, at a minimum, we've got two threads. Dave Watts, CTO, Fig Leaf Software http://www.figleaf.com/ voice: (202) 797-5496 fax: (202) 797-5444 __ Your ad could be here.

RE: Performance boost with Upgrade to dual processor ??
The answer is no the operating system determines the processor usage. When processor 1 is all used up, then the OS instructs the system to begin using both processors to carry the load. Only one processor is used during minimal usage. This might have been true for earlier OS's, but NT and 2000 definitely take advantage of multi-processors All of our servers (apart from one which is about to be upgraded) run on 2 processors and when a heavy request or multiple requests come in, you can see both processors bobble with responses From speaking to an Intel rep at DevCon 2000, they had an 8 processor machine there to demonstrate that CF would happily work with that many processors - I think he gave some stats that it worked out that each additional processor gave roughly a 60% increase in speed compared to a single processor - thus 2 procs=160%, 3 procs=220% etc. I've noticed a MARKED increase in speed on servers with dual processors after the 2nd is installed... On a side note, we also never put below 640Mb RAM into any of the servers, it's not worth going below 512Mb these days...

You have one thread responsible for listening and directing requests to worker threads, and you have N worker threads, N being the number specified in the simultaneous requests setting in CF Administrator. So, at a minimum, we've got two threads. Actually all you have to do is bring up the task manager and look at the three CF processors with thread count turned on :) and... I'm getting 38 threads total for CF 5. The max is 32 CPU's they said under Windows, so a couple cpu's would have to share but that should MP nicely -- assuming they've thought how to distribute load through the threads's properly. --min __ Get the mailserver that powers this list at http://www.coolfusion.com FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Archives: http://www.mail-archive.com/cf-talk@houseoffusion.com/ Unsubscribe: http://www.houseoffusion.com/index.cfm?sidebar=lists

Well, I have been involved in two operating system projects, one as recent as last year -- and I've actually, among other things, written a protected mode boot-strap loader for a multi-threaded-system, so I'm probably more familiar with how cpu's do context switching and SMP on Intel's and AMD's than most folks here That said, in general the answer would be yes. It it possible to do such with only one thread (the parent process) but it would be so inefficient (and such a great struggle to do otherwise) with a large server app like CF that they most likely would have to take the easy and scalable way. Btw, I just looked and a fresh install of CF5 here is using 38 threads at the moment. :) --min __ This list and all House of Fusion resources hosted by CFHosting.com.
