Title: Re: [amibroker] Off Topic: Optimizing a PC for Amibroker Backtesting - What's most important?
I think drive performance is the #1 area since we deal with databases. However, Amibroker caches all info so it may not affect AB as much as your data supplier.
I read a performance report in MaximumPC, who always thought RAID 0 was the way to go. A couple months ago they decided that RAID actually slowed down gaming performance (which is their focus). I know, it’s not supposed to do that, I’m just quoting what they found. Memory depends on how many apps you have open at the same time. For example, Excel takes up nearly 1/2 GB. I certainly wouldn’t buy less than 1GB of RAM.
Extreme Edition costs quite a bit extra and is primarily for gaming performance.
I would get a video card with at least 64MB of RAM, 128 is better. This is for the 3D optimizer displays.
So, 3.0 GHz processor or better, 1GB RAM, SATA or SCSI 10,000 RPM drive, good graphics card (the latest top performers are Nvidia GeForce 6800 or ATI Radion X800, but lesser cards will do).
PS: I’d be inclined to go RAID 1 for the redundancy since I think that’s more important than speed where you are investing your own money.

Subject: [amibroker] Off Topic: Optimizing a PC for Amibroker Backtesting - What's most important?
I am looking at getting a PC dedicated to running Amibroker backtests and was wondering if anyone had any input on what the most important performance attributes would be.
I am thinking of an Intel Pentium Extreme Edition or Athlon 64 FX-55. It seems the difference is that the Intel has a bigger cache which seems like that could make a difference. Also TJ once indicated that hard drive performance is important so one might think that a RAID 0 with 2 WD 10,000 RPM drives might be the way to go if that is true. Lastly, it’s not clear if memory beyond say 1GB would make much difference.
Has anyone tried to come up with the fastest backtesting PC or have any opinions on what attributes of the PC would be most important. I suppose one could optimize everywhere but that could be overkill.
Thanks for any insights.
Tom
