Even with this insane user count, bandwidth remained totally saturated. The user count could have been higher, but the machine ran out of processes. vsftpd is now a proven stable solution. Of particular note, RedHat used vsftpd to enable ftp.redhat.com to support 15,000 concurrent users across their server pool. This extreme load was generated by the release of RedHat 7.2 to the world.

Dokolkoto sym zapoznat s wyprosa vsftpd nqma standalone mode. W kombinaciq s xinetd tyrkalq ftp.redhat.com . Ideq si nqmam kak tochno sa go tune-nali no towa e fakta. Za wseki now user se startira otdelen vsftpd proces, kojto si chete konfiguraciqta i ot tam natatyk se zanimawa sys wsichki dejstwiq po syotwetnata controlna konekciq. Dori ako trqbwa da sme tochni puska dwa procesa, poradi priviledge separation modela mu.
