Hi Victor
what ideal configuration of a machine to use koha with 50,000 records and 200 administrative users accessing the adm interface for loans and returns? CPU Memory HD....
Personally I would suggest a virtual machine with 2 CPUs, 4 GB RAM and 50 GB disk space on one partition. Using Debian GNU/Linux 9 as the operating system. Also think about another place to regularly save your backups (for example your local machine or any other host). Many providers offer such virtual machines for less than 60 Euros per year, for example here: https://contabo.com/?show=vps Best wishes: Michael -- Geschäftsführer · Diplombibliothekar BBS, Informatiker eidg.
