Hi Hernán, I don't have any official results to point to on concurrent user testing. But, I will note that it is highly dependent on the amount of memory and database connections you provide to your DSpace site.
The number of simultaneous database connections allowed by your DSpace is specified in your "db.maxconnection" setting in dspace.cfg. This should roughly correspond to the maximum number of database connections configured in your database layer (in PostgreSQL this is the "max_connections" setting in your postgresql.conf, see https://wiki.postgresql.org/wiki/Tuning_Your_PostgreSQL_Server). Keep in mind, DSpace uses some database pooling by default, so you can often achieve more concurrent users than connections (though too many more and you may start to see the site slowdown or start to hit pooling errors). I've done some basic concurrent tests on our end for small sites, and have found very small site (1-2GB of memory, db.maxconnections=75-100), you can support around 100-150 concurrent users (with decent performance...once you hit 150 or so, the site starts to slow down a bit). So, that's a lower level data point. I don't have tests for higher performance, highly active sites, but hopefully others could share their production settings and what sort of concurrent users they've found they are able to support.
