Perhaps, but personally I've never had a problem with it, though I'm far from the usual. I've always been on many platforms, though since discovering Hive I spend a lot less time on most of them. Only the sovereignty-driven social blockchains keep my unwavering attention.
Honestly I have no idea, as I've never used a VPS. The Qortal software runs quite well on a pretty wide range of hardware, also the core can be run on one system, and the UI on another, with communication via ssh. In terms of blockchain nodes, Qortal's is fairly light weight. 😁🙏💚✨🤙
