AMD Single CPU Dual Core Opteron 175
73 GB SCSI Hard Drive
this server heavily uses mysql and apache, php. And this server is in USA. I want to know if below server can give same or near performance. Since I want to move to europe for low ping times from our country. Server in EU is,
IO is better in the Opteron system to be correct and the SCSI will help greatly with that. AMD's dual core knocked Pentium D out of the market as well so definitely pick the AMD 175 SCSI over a Pentium D SATA.
I'd always choose Opteron or X2 over Pentium D...
I'd look for a different server to move to, I don't think you'd get the performance you want with that server...using RAID0 on the SATA would improve the performance but the Pentium D was a poor attempt at Dual Core...see if you can get opteron or woodcrest (xeon 5100 series or core 2 duo)
We have some Opteron 265 dual-core, dual CPU servers, and a fair number of Intel 940 (Dual Core 3.2GHz) servers. Apart from the CPU's these Servers have similar specs (Raid 1, hot spare, 4GB ECC RAM, Windows 2003 standard), and my own experience is that the Intel servers are much faster. All the servers are Supermicro, they were all purchased at the same time, and they are all working as web servers.
My impression is purely subjective rather than being based on any benchmarks, but I am disappointed by the performance of the dual-core, dual CPU AMD's since I was expecting more from them.
If I had the choice in the future, I'd personally purchase Intel - particularly now that the Conroe and Woodcrest cores have been released - since my own impression is that the D940 Intel servers are faster.
Woocrest / Conroe can't scale more than 4 physical CPUs, AMD can.
The more cores you have (4 in your case), doesn't mean the faster the server. If you know what you're doing, you're meant to optimise the system, not expect the machine to automatically boost performance by 50% - 100%, unless ofcourse you're using some kind of dynamic software.
My guess is, you haven't setup the machine properly. But if you have, please let me know what you've done so I can get a better understanding of the situation.
There is no way a Pentium can beat AMD if both are setup to their maximum capabilities.
