by default ti pouzil aes128-ctr, ved si skus ten arcfour a uvidis ci sa to zrychli

skus pridat do scp prikazu -c arcfour alebo si do .ssh/config pridaj:

dodatocna otazka... je sifrovanie singlethread proces? to by vysvetlovalo to ze cpu nie je vytazene...

well ide to trochu rychlejsie...
[root@osdmgpbsdnapp1 mp1]# scp -c arcfour aaa.dat root@127.0.0.1:/dev/null
root@127.0.0.1's password:
aaa.dat 4% 199MB 34.8MB/s 01:49 ETA
ale chcel by some tak 100 MBps
je este nejake stupidnejsie sifrovanie (ziadne sifrovanie)?

este mozes skusit -o 'Compression no'

k otazkam vyssie, sifrovanie je dost narocna operacia, takze to je normalne. sifry su asi dost tazko paralelizovatelne, plus dalsie limity ako ze CBC zo svojej podstaty musi mat vysledok predchadzajuceho bloku kym moze sifrovat dalsi.

btw 34.8 MB je takmer 280 Mbit (neviem ci si naozaj myslel MBbit) a napriklad u mna to na Gbit sieti je bezna max. hodnota prenosu na mechanickom disku (t.j. ani nesifrovane FTP neda viac). to je podla mna bottleneck u teba, ale neviem co mas za cpu

U mna MBps = MegaBajt/s, my sa tu hrame na velky datawarehouse takze chcem mat prenosy 100 - 500 MBps, mechanicke disky su bottleneck len kym nemas RAID, a viem ze tie disky dookazu dat tak 250 MBps, takze to s tvojou pomocou mozem obmedzit na cpu. Netusim co su to za servery, ale asi nejake smejdy a-la vmware lowcost.
Kazdopadne si ma nasmeroval spravnym smerom a dlhujem ti dve zmrzliny :)
