without wanting to be offending or anything but you are missing the point.

Its not about under which operating system SC performs better, its about how SC can perform better under Linux.

Anyone interested running SC under Linux or even MacOS is because they already using this operating system, or want to use it, obviously any compromise in performance is something each individual treats differently, but the first step is for anyone to decide why they want to use a different operating system in the first place.

but wine can't do it and uses only one core
- no multicore support

This does not make sense to us. And also the question is are you referring to cores or are you referring to threads? There is a difference.

The reason this does not make sense because it is up to the application program, to create threads. Those threads are going to run on CPU cores and which core they run on, is going to be managed at the operating system level. It is not up to Wine. Wine simply cannot control this. Or if Linux gives an application the ability to control what the core a thread runs on, we do not know why wine would bother controlling that.

And there is no reason for Wine itself to be creating its own threads and doing other processing. It is just simply passing operating system function calls off to the Linux OS.

And other than graphics processing, the performance of Wine is irrelevant since during normal operation most of the execution time in Sierra Chart aside from graphics, is not passing through operating system code, but is just Sierra Chart's own code not involving Wine at all. Sierra Chart is specifically designed, to minimize the time in the operating system.

And once we remove, all of this MFC specific code and the use of the Windows common controls, and just go direct to the OS for basic window creation and management, then that is going to make even further of a difference. This is in progress and a lot of progress has already been made. The only area where it is difficult to avoid the OS is graphics.

Multi-threading has been supported for awhile now.
We never knew it was not supported. Multithreading must always have been supported by Wine.

Multi-threading support exists in wine and it performs fantastic.

it was addressed as a bunch to ignorant users and not to pro devs

I'm quite familiar with MMU, Protected mode, HT hw, MT sw, IPC, Scheduling and so on.

windoze is OS, and wine is not. in this case one should consider linux kernel + X11 + wine. Sure.

And other than graphics processing

Is there any headless mode for SC?
You must be just kidding here!
So graphics performance is the main bottleneck for SC.
And this one is the only point to consider.
This was pointed at as an inefficient on linux/wine by design.
And you have no any chance to solve it in the nearest future, imo.

Make love not war!
Peace for all forever!
and so on.

It renders on GPU just awful to windoze.
That's the fact.

If you tick the option "Use GPU for Chart Graphics" it's really causing several issues this I also confirm. You just need a modern CPU and you are gonna be fine without enabling this option.

Apart from that, from my personal experience, in order to get rid of issues on Linux in general regarding GPU you better use an AMD card with either the open source or proprietary drivers. NVIDIA really sucks unless its used in headless mode, switched to AMD few years ago and I never looked back.

100% except for games, video editing and CUDA-depend cases

but ... windoze will be triple better for SC gpu rendering

:)

btw: apple m1 unified memory looks great in terms of GPU performance.

For games better on AMD on my experience, video editing again AMD cause with NVIDIA you get a bad desktop experience anyway. For CUDA depended cases then NVIDIA is a must ofc.

You can check my youtube channel for proof regarding the above.

but ... windoze will be triple better for SC gpu rendering

But please read my first comment :) If windows is an ok operating system for you np! use it :) For us and specifically on threads like this, we care about Linux cause we made the choise to use it.

So there is no point arguing if its better on windows, no point at all. We better argue what experience is better on Linux, ertrader I see uses Mint, I use Ubuntu, he uses NVIDIA I use AMD, lets push more information and solid facts here so other people interested they can benefit.

Looking for good non-windows solutions and we sure have found them..that is why I started this thread and appreciate the solid guidance from Linux users to make it even better!

So there is no point arguing if its better on windows, no point at all. We better argue what experience is better on Linux, ertrader I see uses Mint, I use Ubuntu, he uses NVIDIA I use AMD, lets push more information and solid facts here so other people interested they can benefit.

UnixManiac:
Yes, exactly!

SC Engineering:
Thank you for the update and good to hear progress on removing MFC code. It's showing up in continued stability and performance!

Err, GPU rendering is a hardware solution, not a software one, so I don't understand your comment. Hardware is generally independent of hardware.

Has anyone had issues running SC and Chrome at the same time under Linux? When I run both at the same time, eventually my Linux box will lock up solid. Nothing in syslog. Happens about every other day.

SC 2248, latest Chrome, Linux 4.9.0-16-amd64 #1 SMP Debian 4.9.272-1

Please do not advise an upgrade unless this specifically refers to this issue. We do scheduled upgrades after evaluation on test boxes, not just ad-hoc upgrades because a new version comes out. :)

Never happened to me but few basic things I would do:

- fire up couple of terminals visible all the time running top / dstat / gpu monitoring utility etc so when it "locks" you can have a recent "snapshot" of what your system was doing.

- ping the host and try to ssh from another computer if available to make sure if this a driver issue maybe or if the whole system goes unresponsive.

This is well known issue with nouveau driver. Install Nvidia blob to solve it.

So looks like you'd better be quiet.
It's friendly advice.

Hi ,
I installed SC on Ubuntu 21 and can use charts, but when opening auto trading spreadsheets it crashes.
Do auto trade spreadsheets require the installation of any additional dll in wine?
Anybody has succeeded in using them in wine?
I can open other spreadsheets from the main file menu, but when linking a spreadsheet to a chart (either study or auto trade spreadsheet) SC shuts down.

Any help it would be much appreciated
Thanks
Hera

Have not had that problem, however I use custom studies rather than spreadsheets for auto trading. If you have an example chart, I'll see if it happens on both my windows test system and Linux.

Hi,
thank you for your answer.
It happens whenever I try to add a onr of these studies:

Spreadsheet System for Trading
Spreadsheet study

to any chart. For example I tried with audjpy intraday chart and it crashes.
This is the error I get

0094:err:rpc:I_RpcReceive we got fault packet with status 0x1c010003

Thanks

On Ubuntu 20.04 + CrossOver 20.0.4 both studies are working fine for me.
