Hi all, Since I commented earlier and I was looking to upgrade my trading computer, I thought I can put in my 2 cents now - as I just replaced my old (Intel Core 2 Quad Q6700 based) trading computer with a new computer. Key specifications are as follows: CPU: Intel Core i7-5930K 3.5GHz overclocked to 4.6GHz Cooling: Corsair H100i GTX liquid CPU cooler RAM: 32GB of DDR4-2133 SSD: Samsung 850 EVO 1 TB Sierra Chart instances: 4 instances are loaded together with an IB trading platform (I am using the 1392 pre-release version of Sierra Chart) Takeaway: 1. The overclocking helps a little and noticeably slightly faster chart loading vs. no overclocking. 2. In an ideal condition, with an ambient temperature about 21°C and with some tweaking of the fan speed profiles, etc., the CPU would briefly spikes up to about 75°C and then settles down at around 61°C. 3. As per the attached screen shot of CPU loading at "launch" of all 4 instances, all 6 cores (the other 6 cores are virtual cores - which is why there are 12 charts) are max out for about a minute while the charts loads (chart is of 1 minute interval). 4. As per the attached screen shot of CPU loading when "running" normally of all 4 instances, 2 cores were almost at zero load, 1 core at about 15-20% load (browser?), 1 core at 50% (probably IB platform?), and finally 2 cores at close to max out at 100%. Comment for Sierra Chart engineering: If you are ever going to make Sierra Chart work with multiple cores, please spread out the loading a bit if you can so the cores operating are not constantly maxed out at close to 100%. Just a thought and not a requirement. |
