Using the geekbench Benchmark browser, comparing single core performance
———
MacBook Pro (13-inch Retina Early 2015) – Intel Core i7-5557U @ 3.1 GHz (2 cores) – 979
———
MacBook Air (Late 2020) – Apple M1 @ 3.2 GHz (8 CPU cores, 8 GPU cores) – 2327
———Might not be 100% relevant to your use case, but some small performance gains have occurred in the last 8 years.
Cheapest M1 MacBook Air on the refurb store right now is £850. If your 2015 is your main machine you will be astounded by the battery and performance differences that gets you.

There’s no way to meaningfully upgrade this machine anyway. The RAM is soldered, the SSD is proprietary (and 500GB already). Nothing else is upgradeable.
Having said that, your 2015 retina MBP is still perfectly fine for basic tasks as-is; 16GB RAM, 500GB NVMe SSD, fantastic display.
I would back up your files, nuke the OS, reinstall everything from scratch (very easy) and see how it goes.
