It should be dynamically determined based on your machine. I have one machine with 16Gb RAM and the MW uses 4Gb, another machine has 32Gb RAM and the MW uses 8Gb. But you can force to use more memory if at the start up you go to advanced settings and enter java related memory -Xms, -Xmx parameters.

Hi Spin,

When you first start MotiveWave, you can select Advanced after clicking on the Options button. You can try changing the heap size but be careful not to make it too large as it could stop MotiveWave from restarting and forcing a complete uninstall and reinstall of the program.

FYI:

When you have 'tweaked' the above parameters over the limit, and MW refuses to start, simply locate the file startup.ini in your home/.motivewave folder and remove the arguments.

No need to remove & reinstall, and you can start experimenting all over again ;)

Hello @albrespirar and welcome to the MW-forums.

I "think" you might be the first known 'Arch-hero' here 😄

My experience with Arch is rather limited, but this line immediately caught my eye :

/usr/bin/motivewave: línea 35: bc: orden no encontrada

Is the package 'bc' installed ? Google tells me it is in the 'Extra'-repository

bc is not part of MW, imo.

Try installing it and report back please :)

Thanks MW Team for the Linux version that works very fast and smoothly on my laptop.
However i have a lease to IQFeed and I can't connect to it in any way (see attached picture).
After read this topic i decided to try and install macOS Big Sur on a virtualbox machine, install lasted MW 6.4.4 and Crossover though the official IQFeed guide and it looks like it works out of the box without any issues.

I'm running Arch Linux up to date and MW 6.4.4
Bash:
java -version
openjdk version "15.0.2" 2021-01-19
OpenJDK Runtime Environment (build 15.0.2+7)
OpenJDK 64-Bit Server VM (build 15.0.2+7, mixed mode)

I also tried with a fresh Debian Buster Live USB and also Ubuntu 20.4 Live USB without luck.

Wonder know if you guys are running IQFeed with MW on your linux machine and if so without any issues ?

Thanks in advance

Hi @Spin, Please check run.sh script which is present in /usr/share/motivewave. If i remeber correctly 2048mb is passed explicitly over there. You can also increase the heap size by clicking on advance on whe workspace selection screen and set how much you want to keep

Hope this was helpful

When you start up MW, you can modify the memory allocation on the startup window:

870


As I have mentioned in another thread, you can't actually do any complicated configuration because the startup scripts are broken:

871

I have reported this problem and suggested they change it, but so far nothing has happened afaik.

Hello @Per and @pj_motivewave and thanks for the tips.

I had tweaked my startup script (run.sh in /usr/share/motivewave on my machine) to settings that work well for me. Everything runs smooth for a while now :)

I have changed the last line to this to get rid of the annoying 'cannot scroll out'-problem:

Bash:
$SCRIPTDIR/jre/bin/motivewave $MAX_HEAP -Djdk.gtk.version=2 -javaagent:"$SCRIPTDIR/jar/MotiveWave.jar" -Dname="MotiveWave"  -Djava.library.path="$SCRIPTDIR/lib" -DUserHome=$

(this was not my find, but @alexjp's: see this post)

@Per , what do you mean when you say "the startup scripts are broken" ?? :unsure::unsure:

VM args typically have key=value, but the startup script they have cobbled together does a cut on the = character, which means that the only VM args recognised are those that don't have any = characters. What happens is that after the first encountered = it drops the rest of whatever VM Args you've entered in that dialogue. It's quite a poor implementation and they should fix it.

Right :)

Now I see what you mean. That does look troublesome indeed.

Thanks for your expert eye on this ! (y)

Hi Spin,

I checked with development and there is no fix for this at the moment as it seems that the issue is likely to be related to a quirk in the os rather than the MW code.

I will let you know if anything changes.

Best,
The bug with scrolling the mouse wheel only functional in one direction is common, affects more linux users of diffrent distributions. I have linux mint and had the same issue.
The problem is solved. Please look into the theme
motivewave and linux performance improvements
Please implement the improvements . They clearly work, bug solved - performance improved significant. Great applause for the community.
