I'll share my experience running Sierra with multiple installs: 1x Install Charts Denali CME top of Book 1x Install DOMS running Rithmic OR 1x install of Older Sierra running CQG. Tracking a fuck ton of symbols through Charts using Denali (754 symbols today, has been up to ~1500) My DOMS instances have 6x DOMS all set to either 50MS: ES, NQ, CL, GC and 75MS: ZN, 6E. I used to have ES and NQ set to 20ms but noticed no difference - so set them back, your mileage may vary and props to you if you can perceive the difference! I am moving away from Rithmic because it DOES lag significantly on a regular basis. I have seen over 20s delay with 1x ES DOM through Rithmic compared to a full suite of DOMS through Denali or CQG. I am not sure if this is an issue with their DTC server implementation, or just Rithmic being Rithmic. I know traders who use other platforms and have experienced similar lag with Rithmic, although not as severely as I have. I have not noticed any delays or lag with Denali from within USA when using Denali Full Depth for DOMS - although it has been a while since I used Denali for DOMS. Only times I have noticed Delays with CQG are either a fault with CQG, or because I move country and forget to have my broker set the correct localized server. You can add the Data Delay to the Trade DOM Header to show data delay easily (although it is kinda long at 13 characters 'DD: -00:00:00' and really only need the last 4 of those digits). Sierra is honestly really light weight in it's hardware requirements, my DOMS instance sits at about 160mb of RAM usage and I have never seen it take up much CPU usage at all (<1% right now after close, I assume it gets higher during volatile events, but I am looking at my DOMS not CPU usage then!). My Charts Instance is closer to 600MB with about 6% CPU. Other platforms I have used, which are written in Java/HTML I have seen use >500MB of RAM and over 15% CPU just to display some DOMS. Honestly - for everyones talk of needing powerful PC's to trade with, the data processing really is minimal compared to what modern computers are capable of. |
