Adobe CEP HTML Engine has 24 instances running consuming memory

Report · Oct 19, 2023

Hello, I'm running ID 18.4 x64 on an MSI computer running 64 gB of Ram, I have all SSD's in my computer a total of 8 TB the C: drive is 2TB with nothing but the OS running Windows 10 pro.

When I look at why my ID is running so slow I see these Adobe CEP Html engines, this morning there was 24 instances that were running and watching my memory High, when moving the cursur in the ID program it literally crawls along, I find myself having to wait sometimes several seconds for the last command to catch up.

I have tried several of the suggested fixes even to the point that if I hear someone tell me "have you tried shutting down and resarting?" I will blow my cork.

I see that the Adobe team is aware of the issue and will be correcting in future upates, I have seen many complaints, I feel like they really aren't a huge rush to get it fixed or the would have fixed bby now. i have been a loyal customer since 2004 buying the full Disk Packages spending $2500 everytime I wanted new updates. In Fact I made mention that they could increase their user base if they would do some sort of monthly fee instead of the high cost of buying the disc's. I currently buy the full package every year without fail, and I need speed not slow down, any body have a real solution please send exact steps to solve this issue. The speed of my computer is great so it has the to be the program slowing me down, I find this happens in PS as well, and I really need speed when it comes to running that Adobe product.

Thanks for any help I can get.

AFAIK, this is fairly normal behavior. Those elements are what drive the ID interface, so it's not random overhead, it's the memory being consumed by the app itself. I rarely see it reach any significant level — ID is taking 150MB total right now, with about that many HTML engines running.

There are other causes of speed issues with ID, including network/cloud resource access and corrupted preference files. ID itself doesn't really demand much from a system, and often runs acceptably on systems a bit underpowered for the other CC apps. Mega-power rarely seems to contribute much to its overall task response times, etc.

Hi @OmniaGuy,

I also see those many processes on my computer so it seems that is normal. However, the CPU/RAM usage is not too much for me. I am not sure if you did look at the following article. If you did not then try the solutions given therein and do share your feedback on what worked and what did not so that the next person with the same issue is helped.

Seems something is wrong with the latest versions of InDesign in this respect. This is being hugely reported in one of the discussions lately.

Both of these questions come up at intervals — from those who discover all those processes running and are bothered by it, and those who see the high-CPU-usage issue.

I'd just like to note that my adequately-equipped Win11 (and former Win10) system have always shown this multiplicity of CEP/HTML engine processes, and have never shown excess CPU usage, either as a result (most of the processes show zero usage) or otherwise. That to me suggests that the latter problem is only a collateral symptom of some other issue and has nothing to do with the related process count.

@James Gifford—NitroPress I have also the same experience as you report, many instances of the processes but most of them with almost zero CPU usage. Having said that, I think so many people suddenly reporting huge CPU usage can't be discounted so something surely needs investigation to zero in the direct or indirect cause for this issue.

I might be wrong, but it seems to me that nearly all posts that report the issue on that thread are made by the same person.

All but one of the numerous users who report the issue subscribed to the forum just now that is especially to post on that thread. Their writing style - and unusual formatting - are surprisingly similar to each other. I'm not saying this issue doesn't exist. I can see how, out of frustration, someone would employ this peculiar tactics to exactly bring some extra attention to this issue. Once again, I might be wrong.
