Hubspot unusable/ super laggy, runs at 100% CPU

[user2384734]

I've used Hubspot for many years. Just started using it recently. 

It's almost unusable. I have a Macbook Pro, Intel 3.0 Ghz, Quad Core i7 with 16GB. Runs plenty fast for everything I do. 

The moment I open up https://app.hubspot.com/contacts, the Google Chrome Helper (Renderer) ramps up to 110 to 120 % of CPU. The fans spin up and the macbook gets super hot. 

It's just sitting on a contacts page. What has happened to this application? I can't continue to use it in this state. Might have to go back to AgileCRM. 

I'm seeing tons of people complaining about this. What is Hubspot doing to address this? Yes, I disabled the Hubspot Sales extension. The only extensions I even have enabled is Bitwarden and Raindrop.IO. These are not conflicting. 

I've cleared the cache of the browser as well. It's definitely the hubspot app that is causing this issue. The moment, I close the Chrome tab, the CPU task that sits around 110% drops off immediately and the computer goes back to normal. 

Why is this happening? Are others also experiencing this? Any solution?

Same issue.  Macbook Air M2, using Safari.  A single Hubspot window was taking 6GB of memory.  Was on the deals page.  I think there is a fundamental issue.  Happy to provide any data if Hubspot engineering will take it seriously.

I see the same problem as the other two, it's regardless of where i work (Both from home, and in the office), so i strongly doubt the internet connection has anything to do with it.

I'm on a M;acbook Air M3, with plenty of power, and i'm using Chrome. I have also tried to set op a new view, and it didnt help. My colleague has the same problem on a Mac Mini M4.

When i'm open just one tab with the contact view, the mac is performing slow. If i'm opening 3-4 tabs on contact view the mac is unusable.

I'm wondering if HubSpot has tried to reproduce the scenario on their own test lab, and what the conclusion might be?

I have a very powerful, new laptop (64 GB RAM, 24-core Ultra 9 275HX). The Contacts View is currently straining two cores, leading to the computer becoming extremely hot and initiating thermal throttling.

[user2384734]

Can someone from the Hubspot team please comment on this. I'm seeing this issue reported all over the internet. Sitting on the Contacts page (one of the primary views when using a CRM should not cause a modern laptop running an i5/i7 chip with 16 GB of ram on a Macbook Pro or Windows laptop to run at > 100% of CPU. 

The moment I open https://app.hubspot.com/contacts, I see the entry in task manager or activity monitor and boom it's already hovering around 114-120 % of CPU. A minute later, I hear the fans go full throttle. Even as I type this and I have the tab opened on Chrome, doing nothing in the interface, it's running at that level. Why the **bleep** would that be? This has to be some horribly designed page that is just running a bunch of nonsense or mining coins while I have it open. 

And yeah, I already checked all the recommended things people have posted about. That's all nonsense. I see the same behavior in Chrome, in incognito chrome, as I do in a fresh out of the box Safari with no extensions installed and nothing else running. And no I don't have hundreds of columns on my Contact view page. I have TEN columns of data and I limit the view to 25 contacts per page. 

So someone at Hubspot should explain why the heck it's consuming all of my laptops CPU and running as if it's mining digital currency.

Hi @user2384734 and thank you for sharing these detailed observations about CPU usage on the Contacts page, we really appreciate your thorough testing across browsers and settings.

Just to help us investigate further, could you let us know the following please:

- Does the high CPU usage occur with other HubSpot pages, or is it unique to the Contacts page?
- Have you tried accessing HubSpot on a different network or internet connection to see if performance changes?
- Are you able to reproduce the issue with a different user account or after creating a brand new contact view?

We’re keen to dig into what could be causing this and will surface your feedback to the product team.
 

Thanks for helping us improve HubSpot, and looking forward to your insights!

I'm reporting the same issue, perhaps some one from Techcnical support should see this.

Im happy to respond the questions you made to @user2384734 

- Does the high CPU usage occur with other HubSpot pages, or is it unique to the Contacts page?
Just the contacts page....

- Have you tried accessing HubSpot on a different network or internet connection to see if performance changes?

The contacts view consumes a lot of CPU in different browsers, differente configurations, after cleaning cache or incognito windows, different computers (the old ones render unusable while the more powerful ones become extremly hot).

- Are you able to reproduce the issue with a different user account or after creating a brand new contact view?

In my account, creating views with only 3 column result in the same problem.

[user2384734]

Thanks for sharing. Based on what I am seeing on other posts and forums, this is not unique and appears quite widespread. I'm confused by how this is not known by the Hubspot team. Hopefully they will acknowledge and address soon. It really makes the application unuseable. I'm currently using an export of the contacts view in Google Sheets to manage the contacts and then periodically update the contacts with an updated google sheets file as I make changes to the custom fields I have added to my contacts. But this is ridiculous.

Hi @BérangèreL 

See my answers to your questions below:

Just to help us investigate further, could you let us know the following please:

- Does the high CPU usage occur with other HubSpot pages, or is it unique to the Contacts page?

No, it seems unique to the Contacts page.

- Have you tried accessing HubSpot on a different network or internet connection to see if performance changes?

Yes, same results. Internet connection doesn't seem to have any impact, and wouldn't assume so. I'm on a 50Mb Down/Up fiber line.

- Are you able to reproduce the issue with a different user account or after creating a brand new contact view?

I will check tonight. 

[user2384734]

Yep, same result with different user and creating a new contact view. I tested with the default Hubspot "All contacts" Contact view. 

[user2384734]

The above was tested on the Macbook I previously stated. I went ahead and tested on a comparable spec Dell Desktop computer. Same result. CPU utilization goes from 64% when NOT on the Contact page in the application to 100% when changing to the Contacts page and viewing any view. It's an issue with whatever you guys got going on in the background on the contacts page of the application. 

[SGammelgaard]

Have the same problem unfortunately. My Macbook Air M3 is running very hot when using HubSpot and it's verry laggy.

I have tried the solution with deleting website data, and it did not work. I have also tried to use Safari, but is also drags almost the same amount of CPU 😞 

I think this system is brooken somehow, and it's very anoying since i use it everyday, and my computer gets super hot, and the battery runs out very fast.

Hi,

What’s worked for me:
Start with a clean Chrome profile (Guest mode) and toggle hardware acceleration off. If CPU drops there, your main profile is the culprit. In your main profile, clear site data just for app.hubspot.com, then hard-reload (Cmd+Shift+R).

Table actions - Edit columns (keep it lean), set rows per page to 25, turn off the right preview panel, and avoid wide all properties views. Saved views with fewer columns make a big difference.

Kill possible reflow loops: temporarily disable Bitwarden and Raindrop, then re-enable one by one. Also, try Chrome Canary or Edge/Firefox, if those are smooth, it’s a Chrome+profile issue, not your machine.

Hope this helps!

[user2384734]

Thanks @TOlis 

I gave your suggestions a try, but unfortunately I'm still seeing the same behavior. It just seems as though there is a fundamental bug with Hubspot. I have no idea why having the page open (once loaded) would require CPU to be running at 100%. I don't get it. I might just have to export my contacts and move to another CRM like AgileCRM. 

I have 13 columns on my Contacts view and limited to 25 per page. No extensions enabled and the moment I open that contacts page (without the right preview panel), my CPU utilization goes through the roof with 111% of CPU with the Google Chrome Helper (Rendered) process. 

It's like they are running a bitc0in miner script on these pages. There is no reason it should be consuming > 100% of CPU when I'm performing no action with the tab sitting in Chrome and not even the Active tab.
