Limitations of CMS Enterprise (Customer Portal)

[AKoprivec3]

Hi there,

I recently got contacted by a potential client about improving their HubSpot CMS portal. They have almost every enterprise subscription and use HubSpot extensivly with 7 custom objects, 8 ticket pipilenes and a whole lot of other mess of entagled data.

Their Portal runs extremly slow and after doing a bit of a dive into the code it didn't see that bad to me. And although half the CSS could be removed and JS optimized all in all I doubt I'd improve the website performance by much.

My question here is what are the exact limitations when it comes to HubSpot on this, is this just something that doesn't function well on HubSpot and is just way to complex to justify not using a modern tech stack on a cloud provider and have that integrate with HubSpot via APIs (also I'm guessing we'd have to go the Developer App route there)

Does anyone have any experience with this and can give any usefull insight? Thank you!
