[Koha] [EXTERNAL] Re: Hardware requirements

[King, Fred]

Our library also runs on Digital Ocean. We have just under 20,000 bibs, and we're getting by with 4GB RAM and 80GB disk. Most of our users go straight to the online journals, so our Koha doesn't get much use except for the few people who want our print and online books. We were running with 2GB RAM, but then I installed Elasticsearch and we suddenly needed more.

This isn't a definitive answer, but we support 6 volunteer-run libraries here in Sheffield on a "Basic Plan" droplet from Digital Ocean with 8Gb memory, 4 vCPUs and a 20 Gbyte disk. CPU usage sits mostly between 30% and 60% (the peaks are around 6.30am when the cron jobs run). Memory usage is quite high (70%) and is the thing we would run out of first if we tried to support more libraries. Disk usage is steady at 18%

Hope this helps!
