RE: Serwer Hardware p4 or pIII ?
Helmut, I suppose that depends really upon the composition of your database. Unfortunately, I am far from an expert when it comes to MySQL or virtually any other database, I just happen to know a little bit about hardware and some performance related information. All of that is only on the low-end commodity hardware of the personal computer. If you know what size database, meaning how many tables and how much information you will have in the database then I am certain that other more database knowledgeable members of this list will be able to offer some suggestions. The only other thing that I can add is if your database is going to be relatively small (In comparison to some of the databases discussed on this list.) you will probably see admirable performance on the fastest Pentium 4 and the fastest AMD Athlon XP+ system you can build or buy.

Its more to do with the amount of memmory than its speed. As MySQL will try and load as much data (tables) into memmory as posible the more the better. The next thing is disc speed.

RE: Serwer Hardware p4 or pIII ?
I saw some discussion on this topic last night, and forgot to put in my .02: Whomever said that memory and hard disk hardware should be the focal point in a new mySQL DB server, and not processors, I very much disagree with. While I agree that ample and fast memory, in addition to an efficient, reliable, and speedy storage system, is vital, neither of those mean squat if you don't have a high speed bus and powerful CPU to do the computations. You can have gigs and gigs of RAM and the fastest SCSI RAID array, for all I care, if it's still on a tiny 100MHZ FSB (like _original_ P3s), you still have a huge bottleneck looming on your horizon. I've been an AMD user for quite some time, and I really think AMD can kick some butt, but I think the statement that P4 FPU performance is poor is not entirely correct. the 2.53GHz P4 is right on par, if not better, than all but the highest (2600+) AMD XP chips. The 2.8 certainly edges them out, and the 3.06 GHz's performance is ASTONISHING. This is based on multiple benchmarks I've either seen or done, so I'm not just talking whitepapers (and keep in mind, I've been a big AMD fan for a couple years now). I refused to be impressed by the performance of Intel's processors, but this made my head spin. As far as cash goes, yes the 3.06 is VERY expensive (around $700 right now), but the other tiers below it are getting ever more reasonable. It comes down to cash flow, I think. P3's strong points is that they are tried and true, powerful, reliable, but inexpensive. P4's fast memory bandwidth, and the upper echelon of P4s are just impressive, but expensive. AMD's are cheap and pack a good punch. I won't go into Xeon, MP, and other multi-proc stuff, that's a slightly different ballgame. I very much agree with mixing and matching different types of boxes based on their strongpoints.

Re: Serwer Hardware p4 or pIII ?
Does anybody have any benchmarks of MySQL running on otherwise equivalent machines but with different CPUs? It would be interesting to compare Athlon vs Pentium III vs Pentium IV vs Pentium IV Xeon at various speeds. And yes, while a Pentium IV is generally slower than a Pentium III at the same clock rate. What happens when you take the fasted Pentium III (1.4 Ghz?) and compare it with the fastest Pentium IV (3.0 Ghz?) or Xeon (2.? Ghz)? Also, has anybody compared the performance of SCSI Raid 1, with IDE RAID 1 using a card like 3ware.com that uses independent channels for each drive? In general, for a particular amount of disk space, IDE RAID, including an extra controller card, tends to be about 1/2 the price (or less) than SCSI. If I used that money and by additional RAM, which will perform better? It would be interesting to have a comparison of machines (possible sponsored by various vendors, AMD, IBM, Intel, 3ware, penguin, etc) that compared machines with the same retail price running some standard benchmarks. Something like http://www.mysql.com/information/benchmark-results/result-mysql-platform-relative.html but with hardware more recent that a 400 Mhz pentium pro. Adam Nelson wrote: I've posted my comments before but the important thing is that P4 is largely unnecessary as it doesn't have instructions that apply to server applications (mostly). So, PIII (dual is quite helpful) the fastest you can get without paying a premium 1 GB ram dual scsi drives (raid 1) This is the simplest scenario and will handle tons of queries (100/sec) with drive failover (very very nice) very fast and it can fit in 1U. If you have less money, I would drop the second proc, then move to lower speed proc, then less memory. -Original Message- From: Nicolas MONNET (Tech) [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 04, 2002 10:46 AM To: Helmut Apfelholz Cc: [EMAIL PROTECTED] Subject: RE: Serwer Hardware p4 or pIII ?

MySQL uses memory and HDD the most and so processor speed is not so important. So I would go with what ever costs me the less. Also how you OS works with the processors will be important. What OS are you going to got for? Threads and OS limits will also play a big part with speed.

I will be running linux on the server. Could anyone share his/hers experience with me ? I have often wondered about that myself so I would be interested in other people's views. I currently run a number of servers with dual 1GHz P3's.

Well, processor speed is also important, on some of our servers processors are almost 100% occupied. So I would go with what ever costs me the less. Also how you OS works with the processors will be important. What OS are you going to got for? It will be Linux, 2.4 kernel Threads and OS limits will also play a big part with speed.

Hi, I am assembling mysql only server. I am planning 2Gb RAM, 4 x 15k SCSI disks. However I cannot decide if I should get 2 p4 processors or 2 tuallatin pIII. I could not find any mysql specif?c benchmarks, that would show which processors I should use. I will be running linux on the server. Could anyone share his/hers experience with me ?

Re: Serwer Hardware p4 or pIII ?
Having the fastest memory that is available in your system is not as important as having enough memory in your system. Without sufficient memory, you can choke your whole system and bring your server to a crawl (or even crash).

RE: Serwer Hardware p4 or pIII ?
I've posted my comments before but the important thing is that P4 is largely unnecessary as it doesn't have instructions that apply to server applications (mostly). So, PIII (dual is quite helpful) the fastest you can get without paying a premium 1 GB ram dual scsi drives (raid 1) This is the simplest scenario and will handle tons of queries (100/sec) with drive failover (very very nice) very fast and it can fit in 1U. If you have less money, I would drop the second proc, then move to lower speed proc, then less memory. -Original Message- From: Nicolas MONNET (Tech) [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 04, 2002 10:46 AM To: Helmut Apfelholz Cc: [EMAIL PROTECTED] Subject: RE: Serwer Hardware p4 or pIII ?
