I know you didn’t ask me, but I’ll share my specs & performance to help:
Without giving specifics, my PC was built in 2013, and since then, only the PSU & CPU fan have been replaced. The internet connection uses a wireless usb adapter. When running Google’s speed test, my download speed gets to about 27mbps, but usually is moderately lower. For comparison, my phone (which is newer) can reach that same speed constantly, so my phone performs better on average than my PC.
For me, in terms of performance, I have never had a problem with the forum. The performance is noticeably better than the old forum. For reference, here’s a video of me scrolling through this entire thread, post-after-post, in 44 seconds (I made sure to clear cache, cookies, etc., to have a “fresh” run):

For comparison to the old forum, with 261 posts (as of this post) at 10 posts per page, this is the equivalent of clicking through 27 pages.
