Wish IDE B4a parameter compilation Java XMX

[bridge1]

Is it possible to add in the B4a (Basic for Android) IDE configuration options the ability to customize the maximum memory (XMX) parameter to compile projects?

To be clear, the following parameter:

"C:\Java\jdk-19.0.2\bin\javac.exe" -J[B]-Xmx2048m[/B] -d shell\bin\classes  -bootclasspath "C:\Android34\platforms\android-34\android.jar" -Xmaxerrs 1 -nowarn -Xlint:none  -target 8 -source 8 -version -encoding UTF-8 -cp "C:\Program Files\Anywhere Software\B4A_1300\libraries\jdebugrapid.jar";shell\bin\classes\  shell\src\project\test\main_subs_0.java

"C:\Java\jdk-19.0.2\bin\java.exe" -[B]Xmx2048m[/B] -cp "C:\Android34\tools\..\build-tools\34.0.0\lib\d8.jar" com.android.tools.r8.D8 @d8_arguments.txt

Have you encountered an out of memory error?

You can change it by modifying MaxRamForDex in the INI file. Change it while the IDE is closed.

Thanks for the reply.
We do NOT encounter a problem of missing RAM, in fact during the compilation we have 8gb available before starting the compilation.
we have verified that by raising the parameter value to 6gb (-Xmx6144m) the problem persists, that is, the compilation is too slow.

We would have the doubt that during the compilation operations, NOT all the available CPUs are used.

Is there any trace file of the compilation operation, which highlights which hardware resources are used?

Specifically, display the number of available CPUs
Runtime.getRuntime().availableProcessors()

Runtime (Java SE 19 & JDK 19)

declaration: module: java.base, package: java.lang, class: Runtime

Can you post the compilation window text?

This is indeed very slow. What are the computer specs?

 

[bridge1]

Build hardware specifications:

• cpu AMD @2.00 GHz (6 core - 12 threads)
• ram 16gb
• ssd 1tb

 

[Erel]

Maybe the CPU is a bit slow. Maybe the problem is somewhere else. I assume that you aren't using a VM or a network drive.

For B4a 13.00 development do you know what the minimum hardware specifications are?
