I used to be the tech lead for the UI and much of the infrastructure behind ovidsp.ovid.com. We regularly had 20000-50000 concurrent user sessions active. Each one had a dedicated backend process, so we had an exact count of active users. The UI served over 1 billion http requests per year... using a custom http server I wrote in Perl :)
