DW Freeze ups when project include RxJS module

This is a dup of DW Freeze ups when project include RxJS module – Adobe Dreamweaver CC: Feature Ideas

I'm evaluating DW product to a number of users in my organization.

There is show stopper problem where the whole application freezes,
becomes unresponsive, for seconds or even minutes at a time with high CPU utilization.
I've issolated the problem to using the very popular @reactivex/rxjs library that is used
in Angular and many other libraries and frameworks.

I've distilled the problem to a 17 line html file and 29 lines of Javascript to load and lighly use
the RxJS library.

I just downloaded the product, so I highly doubt the issue is based upon any changes I've made to the configuration.

The issue has been seen on
Adobe Dreamweaver CC version 18.1 10155 build
"Standard" mode
on Windows 10 Pro, 64 bit.
10.0.15063 Build 15063
System Manufacturer Dell Inc.
System Model Precision 5520
System Type x64-based PC
System SKU 07BF
Processor Intel(R) Core(TM) i7-7820HQ CPU @ 2.90GHz, 2901 Mhz, 4 Core(s), 8 Logical Processor(s)
Total Physical Memory 31.5 GB
Available Physical Memory 17.6 GB
Total Virtual Memory 36.3 GB
Available Virtual Memory 21.2 GB
Page File Space 4.75 GB

To reproduce the problem.
a) extract the project attached .zip file onto a directory
b) if not already installed, install nodejs and npm
c) run command prompt command "npm install" (this step will gather rxjs and systemjs from the internet)
d) open up the index.html file in Dreamweaver
e) note that the application becomes unresponsive every you switch views for long periods of time. The CPU utilization goes very high during this period.

    Thank you for logging the bug.  Have you been able to reproduce the problem with the distilled project I provided?

    I don't know much about RxJS and by the looks of the number of replies that you are getting, it may be that you are a loner on this forum.

    Having said that, and using the limited amount of logic that I have left (reached saturation point many moons ago), I would suggest that RxJS is not the problem. I say this because RxJS is a JavaScript library similar to

    • Google Polymer
    • Dojo Toolkit
    • jQuery
    • midori
    • MooTools
    • Prototype JavaScript Framework
    • etc., etc., etc.

    and Dreamweaver has no problem with any of these libraries.

    Which leaves us with your mode of installation. With the knowledge that Dreamweaver uses CEP and CEP relies on nodeJS,

    • Could it be that there is a conflict somewhere?
    • Have you tried using a CDN rather than installing the library locally?
    • Have you tried restarting your system after installation?
    • Have you had a look at Task Manager to see what is causing high CPU and/or Memory usage?
    • Have you had a look at crash reports to find the problem module?
    Wappler is the DMXzone-made Dreamweaver replacement and includes the best of their powerful extensions, as well as much more!

    To answer those questions.

    Which leaves us with your mode of installation. With the knowledge that Dreamweaver uses CEP and CEP relies on nodeJS,

    • Could it be that there is a conflict somewhere?

    Maybe.  I don't know anything about CEP.   This is the version

    Version of node is

    C:\Users\rseroka>node --version

    v8.11.0

    • Have you tried using a CDN rather than installing the library locally?

    If adobe can't reproduce the problem with the 46 line project I provided them, I will take the effort to try this.

    • Have you tried restarting your system after installation?

    Yes.  No better than before.

    • Have you had a look at Task Manager to see what is causing high CPU and/or Memory usage?

    Adobe Dreamweaver CC 2018 is the by far highest process by CPU in taskmanager. 

    Dreamweaver.exe is the by far highest process by CPU in resource monitor.

    • Have you had a look at crash reports to find the problem module?

    It's not crashing.  It's just not responsive.

    This is my Task Manager

    Comparing this to your results and finding the reasons for the differences would be an interesting exercise.
