I have noticed that Sierra uses a lot of CPU time on my Linux/Wine setup. My brand new PC has 32GB and an 8-core AMD 8350 with 2 DVI-monitors at 2560x1440 resolution each. ; "top" output looks like this: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1976 jan 20 0 2043320 1.699g 21924 R 71.7 5.4 103:27.32 SierraChart.exe 1948 jan 20 0 20000 8712 768 R 47.2 0.0 70:07.09 wineserver and the fans start blowing off steam as soon as I start Sierra/Wine. I should add that currently I am keeping about 35 chart books open, with some 10 charts each, where each chart book tracks a different symbol using IB. Is this normal? If not: any suggestions on how to get the cpu load under control?

This is outside the scope of our support. We have no control over this. It should be understood that the use of Wine is not efficient. We are marking this as a user discussion. We expect by the end of 2014 we will have a version of Sierra Chart that will directly run on GNU/Linux. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users. Try to keep your questions brief and to the point.

Thank you; understood. However is there anyone else using Sierra under Wine with similar or different experiences? Date Time Of Last Edit: 2013-08-19 09:05:15

User59879 hi The X Window System is outdated. It has less efficient GUI subsystem comparing to MS GUI subsystem. Wine translates MS API into the inefficient X. We are waiting for Wayland. It should solve this - I hope it will work fast and stable using video hardware acceleration. In order to distribute/optimize the load you could use: - proprietary drivers for video cards - crossover with the separate "bottles" system for SC instances - ssd imho gd lck

Thanks User59879, I am using the open source nouveau graphics driver, that might indeed be the problem. Will look into that this weekend and report back.

User59879 yes. you should use a proprietary driver to decrease the cpu load. this is the most important step in order to use charts gd lck

User59879 are you using 32bit or 64bit distro? 32bit distro w pae-kernel will able to use 32G RAM Wine will work a bit faster using native 32bit environment gd lck

I'm using 64 bit Arch Linux distro. Speed is not really an issue here though, but cpu usage and fan noise is ;-)

User59879 ok. let me rephrase it in order to prevent a lot of transitions from one environment to another one need to use 32bit distro for Wine it definetely will decrease the cpu usage gd lck

Thanks a lot; I will build a new linux distro on a separate partition (probably this weekend), including proprietary nvidia drivers as well as 32bit distro for Wine and let you know the results :-) Date Time Of Last Edit: 2013-08-19 16:58:36

I'll be interested to hear how it goes too. I'm using Nvidia 313 proprietary drivers on a 3.8.0-27 kernel on Mint 15 x64. I don't see those sort of issues but I'm only opening two chartbooks of about 5 charts each. My 4 cpus run at 1600MHz (half speed) with Sierra around 12% and wineserver around 5% (of one cpu). I just opened another 8 and that took the (single) cpu up to 36% so I can see 70% being reached easily enough with your number of chartbooks. Note that unless I'm reading top incorrectly the other 3 cpus are doing other things. No, I just discovered what happens when you press 1 on top ... its nicely spread amongs the cpus which explains why they're all still running slow. http://i.imgur.com/NJmW1rR.png

hi all i've done the test using old laptop Intel(R) Core(TM)2 Duo CPU T5900 @ 2.20GHz 4G RAM 128G SSD GF GT220M openSuSe 12.3 32bit xfce nvidia v319 wine1.6 SC v1013 non-CLR CTS FIX 35 chart books open, with some 12 (tick-based and 1-minute-based) bar charts each; using some custom DLL and VbP the cpu usage is http://s24.postimg.org/p07xi00gl/sys1.png gd lck Date Time Of Last Edit: 2013-08-20 08:14:09
