Nextcloud vs OwnCloud Performance and Hardware Needs Honest Guide
No invented benchmarks - the honest performance picture. Architecture, real bottlenecks, and what hardware a home or small office actually needs for Nextcloud or ownCloud.

Every comparison page on the internet will quote you a speed number for these two platforms. This one will not - because a benchmark from someone else's hardware tells you almost nothing about yours. What transfers is architecture and bottlenecks. Here is the honest version of both.
What actually makes a home cloud feel slow
Disk speedthe storage underneath beats the app choice
Upload bandwidthyour internet line, not the software
Preview generationfirst-open thumbnails cost real CPU
The office serveroften hungrier than the file server
In a small install, the platform is rarely the slowest part of the system.

Architecture - Why oCIS Has the Higher Ceiling
ownCloud Infinite Scale is compiled Go, running as microservices with no central database bottleneck, designed from a blank page for thousands of concurrent users. Nextcloud is PHP: every request spins up application code against a database, which is heavier per request - a design that trades raw ceiling for its enormous app ecosystem. Vendor claims of many-times-faster performance for oCIS are vendor claims, but the direction is credible: at institutional scale, the Go platform is built to win. At five users, both idle along far below what your hardware can do, and the ceiling you never reach decides nothing.

Nextcloud Tuning - The Gap Closer for Small Teams
Most of Nextcloud's real-world slowness is configuration, not destiny. Run background jobs by system cron instead of on page loads, add Redis for file locking and caching, keep PHP and the database on the same fast disk, and let preview generation happen on schedule rather than at click time. A small office that does these four things stops thinking about performance entirely. ownCloud Classic shares the PHP shape and the same tuning logic; Infinite Scale mostly removes the topic - there is simply less stack to tune.

Sizing Guidance Without Fake Numbers
Family or tiny team, files only: a modest VPS or mini PC with a couple of GB of RAM serves either platform - put the money in disk and backup instead.
Add office editing: give the editor server its own real share of RAM and CPU; this is where small installs actually feel strain.
Many users or huge libraries: this is where the architectures part - Nextcloud scales with tuning and infrastructure, Infinite Scale was designed for it, and institutions should trial both under their own load.
Either way: an SSD under the data and an honest upload speed matter more than the logo on the login page.
Reading rule for this whole topic: when a vendor page says one product is many times faster than another, ask at how many users, on what storage, doing which operation. If the page does not say, the number is marketing - on both sides of this comparison.

The video runs both platforms - watch the day-to-day feel of each, then size your own box with the rules on this page.
At large scale, ownCloud Infinite Scale - that is what its architecture is for. At home and small-office scale, a tuned install of either feels instant for files, and your disk and network will decide the experience long before the software does.
Can either run on a Raspberry Pi or old PC?
Both can, and both are run that way by hobbyists. Keep expectations honest: file sync for a family is fine, browser office editing and heavy preview work will test old hardware on any platform.
Do I need an SSD?
Not strictly - both run on spinning disks. But the database, thumbnails and app code all live on the system disk, and an SSD there is the single cheapest speed upgrade for either platform.
