Extremely slow DW file loading and editing response

Hello
I am having performance issues with Dreamweaver that has been going on for weeks. Namely extremely slow response to loading-file-to-scroll times and extremely long response times for editing.

Typically loading a small standard html file takes 40 seconds, 20 seconds of which is a white screen in the editor and the other 20 seconds waiting for the mouse to be able to scroll. Then I enter a single letter and another 20 second lag before the cursor updates. It is unusable for development work. I have been using DW for fifteen years on my site and it has never performed so poorly.

I have 16 GB RAM and the total computer typically uses 11 GB with DW taking up 3.5 GB

Here is what I have tried according to the forum and AI assistance

1. Do not have live view enabled - I never have, so irrelevant
2. Switch off code hinting - no effect
3. Switch off site cache in the site console - no effect, bad with and without cache

4. Cleared site cache and rebuild - done several times - no effect
4. Check latest update - Adobe creative says it is up to date

    Correct answer Ben M

    Since it's only happened in recent weeks has anything changed recently? Is the site located on the local computer or a network drive? Being that the computer is using up 14.5GB of 16GB of ram, it's possible as well that if something else changed or now uses more memory that your memory may be at its limits and it may warrant an upgrade.

     

    To the points you have tried:

     

    1. Are you saying that you are working entirely in Code View if you are not using split/live view?

    2. I wouldn't see this having a major impact.

    3/4. Have you reset preferences or only rebuilt cache? If you have not tried resetting preferences try this: https://helpx.adobe.com/dreamweaver/kb/restore-preferences-dreamweaver.html

    5. DW hasn't been updated in quite some time as it is in minimal maintenance mode so I doubt if the problem is recent that it was caused by a DW update. As such considering alternatives may be the best route to go depending on your development needs.

    I am having the same problems for the past couple of months and it seems to be getting worse.

    I only run in code view and have tried all the suggested solutions, I have today doubled my RAM to 16GB, and still it takes sometimes 5 or 10 seconds to be able to work with the code, either scrolling or typing, highlighting etc, happens when I load a new page or when I leave Dreamweaver, to view browser or similar and then return to Dreamweaver, a massive lag.

    I am not having problems with any other program and nothing changed on the PC, have 500gb SSD and work locally.

    Same, my DW is unusable and I'm tranistioning over to VS Code. I'm also tranistioning from Premiere to Resolve. Our firm pays  a few hundred per month to Adobe for broken software. It's frustrating that Adobe does not care at all.

    In the past month my DW is close to being unusable. Typing is slow, double-clicking a word (string) is painful. I double-click and nothing happens or the entire line is highlighted. Selecting lines of code lags (seconds). Typing in any way is delayed.

    I cleaned out the cache and tried every thing except an uninstall > install. 

    Moved to VS code in the mean time.

    ===========

    Did you Restore Preferences?

    Did you wipe old DW files off your system with the Adobe Cleaner Tool before reinstalling?

    Restoring preferences did nothing. 
    It's as if the keyboard buffer fills up after 3 or 5 keystrokes. No other app on my system does this. I tested a few different USB and wireless keyboards and the keyboard on my laptop.  It feels like there is so much latency in DW. 

    I do not want to run the cleaner tool on my system at the moment.

    • Which version of Dreamweaver?
    • Which operating system?
    • Is your local site folder defined and residing on your primary hard drive?
    • Have you tried Restoring Preferences?

    I followed the reset preferences solution and it seems to have worked. Thanks for your help. Hopefully the problem won't come back again
