Learn how to cache your application and your cpu usage should be almost zero. In fact basically any read should cost nothing in comparison to writes.
The following from Claude: """ A diff between two randomly chosen commits usually spans years of history, so it's not a few KB — the tree itself is ~1.5 GB of text, and a multi-year span rewrites a large slice of it. Call it 100–200 MB per pair on average: 8.5×10¹¹ pairs × ~2×10⁸ bytes ≈ 10²⁰ bytes, or ~150 exabytes """

I can tell.
Imagine if WooCommerce had a route "/product/<sku1>/compare/<sku2>" which displayed an auto-generated comparison between any two product pages.
Now imagine running a million-SKU WooCommerce site, where each product page was 100kb of text.
Now imagine scrapers are permuting those URLs.
How would you cache that?
That's what cgit/kernel.org and many other Git forges are dealing with. These aren't static websites, even if the underlying Git repo is largely static; they're rendering arbitrary diffs and other generated-on-the-fly views into Git history. The ability to do that is a large part of the value of a Git UI.
