zatezove testy

Dva kousky Asus wl500g vedle sebe, v rezimu 'acces point', wifi nastavene na 'hybrid' spojene pres WDS.

Pokus: server PC/linux --switch--100baseTX--- wl500g-A <<< vzduch 10cm >>> wl500g-B --switch-100baseTX -- klient PC/linux

Nastaveni jednoho: [1] Nastaveni druheho: [2]

V obou originalni FW od vyrobce 1.8.1.9, wireless mode: 54G only.

(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.

(2) PINGY typicky ping pres celou sestavu: 64 bytes from 10.107.x.x: icmp_seq=39 ttl=64 time=1.86 ms ... rtt min/avg/max/mdev = 1.806/1.962/3.696/0.381 ms

postupne zatezovani obou smeru 1:1 pingem: ping -n -c 300 -s 65507 -i <interval> server rychlost v kbytes/s merena pomoci iptraf -d eth0

Prakticke maximum, ktere pres to tedy protahneme, je 1.8 az 1.9 Mbyte/s.

(3) STAHOVANI pri 802.11b only 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 2.2 Mbytes/s.

(3) PINGY pri 802.11b only 64 bytes from 10.107.x.x: icmp_seq=164 ttl=64 time=1.48 ms rtt min/avg/max/mdev = 1.352/1.637/13.553/1.080 ms

0.03      890  1930   2850   63%   98ms

Je to divny, ale pri nastaveni 802.11b only je to rychlejsi
