B4J Question Request for help due to scalability problem

Hello!

Im part of a company and we are currently carrying out several web application projects using B4j and Abmaterial, and the use of these tools has allowed us to greatly streamline our processes and has also allowed us to advance in our objectives in a very agile way. However, one of our projects, which is the most important and extensive in this moment, has generated some inconveniences associated with the number of modules that have been developed and we are sure that the problems that are happening to us are due to the fact that we have more than 130 modules (between classes and code), since these same problems do not happen to us in small projects of less than 20 modules. The problems that are happening to us due to the aforementioned are:

- Slowness at the moment of compiling in debug, happening in many cases errors that conclude the complilacion or freeze the b4j.

- The system.memory.exception error is frequent while we are working.

- Freezing of the b4j while we are writing source code.

- The hot code swap on the compiled version (Ctrl + S) stops working.

We are using a development enviroment with this specs:

- Intel i5 or i7, 7th generation.
- RAM 8 or 16 gb.
- Windows 10.
- java jdk1.8.0_202.
- B4j V7
- ABmaterial v 4.51

Due to the aforementioned, we thanks support if there is a possibility. If there is any corporate or x64 version that allows us to improve the performance of this great tool or any improvement that we could apply to solve our problem, we thank you in advance for your help with this.

Thanks a lot.

Are you using a shared network drive for your work? If yes, try to edit/debug your project on a local drive.

PS: Never had similar issues, even if I work for hours

I LOVE to use B4J. I am sure @Erel fix it . Please share results ...

Not: My solitions for my problems; Its maybe halp you.
I didit change my project code.
  • Delete Object folder
  • I had more than one JAva version. I deleted all. I re -insatall last versiyon JAVA 1.8.202
  • Delete b4j and re install (this was my first choice and it didn't work.)

Hello!

Thanks a lot for answer Mr. Erel.

1. Compilation windows text:

B4X: 
Waiting for debugger to connect...
Program started.
Start B4J Analyse!
When an error occurs, check the B4JAnalyse.log file in the Objects folder to see the last B4J line it was working on.

Hello!

Im in the same situation, i really love B4j but im little worry because our project is growing quickly and we have this problems that generate a delay in the development.
In relation to the attempts to solve the problems, I did the same as you, i updated my version of b4j from 6 to 7, updated my java from 111 to 202 and even the Abmaterial took it to the latest version 4.51, but still continued with the problems i mentioned. I hope we can find the best way to solve this problems to keep growing with this wonderful development tool.

Thanks a lot!

Why are you setting the VM heap size to 3gb? You are probably running out of available space. Set it to a lower value during development.

Hello! the truth is that I did it as part of my tests, I tested it in 1024, 2048, and even 6144 but the problems remain.

Thanks!
