(1) RYCHLOST Rychlost stahovani pres SMB server->klient pres 2 switche a 2 asuse, mereno pomoci "iptraf -d eth0":
incoming rates 760 kbytes/s (+-50 se to pohybuje) total rates 800 kbytes/s (+-50)
Rychlost stahovani pres FTP server->klient pres 2 switche a 2 asuse, mereno pomoci gkrellm: aktivita na sitovce ve spickach mezi zapisy na disk (ktere to zpomaluji) dosahuje 1.7 Mbytes/s.
