A tady je vysledek testu cteni :-)

eserer:~# hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   3432 MB in  2.00 seconds = 1716.14 MB/sec
 Timing buffered disk reads:  228 MB in  3.01 seconds =  75.68 MB/sec

Proc tyto switche? Tyto switche budou - po dukladnem testovani - pravdepodobne nasezeny na paterni sit - ne ze by MGS routery to neumeli, ale rekneme ze L3 switche maji lepsi predpoklady k vyssimu vykonu na paterni sit, ale nehodi se k filtrovani paketu dle pravidel apod...

A tady je par vysledku testovaneho L3 switche

1 minutovy test (ping o velikost 65KB-fragmentovan) - zatez cca 160Mbit (80+80)

--- 192.168.102.9 ping statistics ---
6478 packets transmitted, 6476 received, 0% packet loss, time 46116ms
rtt min/avg/max/mdev = 12.060/12.268/14.688/0.147 ms, pipe 2

Odezvy v rozptylu 3sekund :) - to jde. (nerpesnost v mereni, provoz
prochazel jeste pres 2 nerizene 10/100Mbit switche)

A ted jeste zatez na hodne malinkatych paketu (test na 10sekund - 2400paket/sec)

--- 192.168.102.9 ping statistics ---
24319 packets transmitted, 24318 received, 0% packet loss, time 12293ms
rtt min/avg/max/mdev = 0.229/0.264/0.395/0.021 ms, ipg/ewma 0.505/0.267 ms

nacpat finerouter linux (nas upraveny linux), takze mame pomerne slusnou platformu (co se tyka velikosti a spotreby) na staveni routeru :)

A proc ze to delam nes tam nechavat puvodni "mikrotik firmware" ? - zejmena lepsi licenci politika :-), stabilnejsi system - a moznost zapojeni do hromadne spravy :-)

A taky vic verim systemu ktery si stavim sam - nez cernym skrinkam :-)
