How big is your program? How slow is your CPU?
Here is my screen for compiling 3000+ lines of code in Release mode. My CPU is fast.

I have a feeling something else is chewing up your CPU cycles (antivirus, backup, indexing, virus, etc.)
By the way your B4A version is 11.2, like mine.

Most of the time is involved in Dex conversion (even with optimization off)

I assume you've tried this:

Increase MaxRamForDex: https://www.b4x.com/android/forum/t...zed-dex-error-need-help-pls.10428/#post-58036

My setting is:

MaxRamForDex = 4096

Note: if you change this setting, make sure B4A is not running, if it is it will just change it back.

You should probably correct the title of this thread to 11.2 to attract replies from other members.

Ive disable the dex optimization but it still very slow to compile.

This is expected. The optimized dexer makes compilation faster.

Nothing has changed in v11.2 related to the dexer step. I guess that you added a library that depends on Google Play Services components.

Increasing MaxRamForDex can indeed make a big difference.

First step is to enable the optimized dexer and increase MaxRamForDex.

I just have MaxRamForDex=4096 and if I enable optimize dexter it takes another 130 seconds to compile.

It is not so simple to measure the optimized dexer performance as it prepares things in the background and the state of these prepared objects varies.

If you enabled #MultiDex then compilation will be slower.
