Turn on BBR. Your slow box gets faster for free.
Default TCP congestion control (cubic) underperforms on cheap VPS with shaky network paths, especially to far-away visitors. Google's BBR squeezes way more throughput out of the same link:
— echo 'net.core.default_qdisc=fq' >> /etc/sysctl.conf
— echo 'net.ipv4.tcp_congestion_control=bbr' >> /etc/sysctl.conf
— sysctl -p
No hardware, no money, just a kernel module that's been built-in since 4.9. Time-to-first-byte for my overseas visitors dropped noticeably. Costs nothing, can't hurt. Try it tonight.
