WordPress limitations

No not exactly but I will warn it will take alot of resourses from your host and could cause your site to crash with alot of pages on it. Depending on how your host package is.
Remember to have your blog page set to another page if it is not about blogging you can do this via settings and reading you may need to make sure to activate or install and activate jetpack.

I do have experience with building my custom themes from scratch, so that won’t be a problem.
On all of my websites I try to use as little plugins as I possible can (Advanced Custom Fields, Yoast SEO, WPCF7)
I try to build most of the functionalities directly inside the theme, what would be my advantage of using Jetpack?

Maybe the Photon option within Jetpack will be useful but on the other hand, the website i’m planning won’t be using a lot of images.
Again, thank you for your assistance.

2,000 posts is nothing. ??

I’ve got one site that uses 5 different custom post types and has somewhere around 60,000 posts, and that grows from anywhere between 30 and 100 a day. This is on a private VPS, but it is shared with some other sites. As far as handling it goes, it’s fine.

WordPress is the same as pretty much every other system out there. It will handle almost anything that you want it to, but if you go too far you’ll need more server resources.

As far s Jetpack, I don’t use it, but I know that it’s good in some situations. I don’t think that it will make any significant difference in server load though.

Ha, that’s what I wanted to know! ??
I’m also hosting on a VPS so I can tweak a little bit when necessary.

Thanks a lot jdc20181 and catacaustic.

I just wanted to make you aware of that I am glad I could help!
