Moje zahadne FTP

Jsem pripojeny pres kolejni sit, linux, ftp klient shellovy ftp.
Rychlost pripojeni vic nez dostacujici.
Firewall vsecko povolene.
I port 21 z kolejni site ven je povoleny.

Proc je ftp tak pomale? To je ftp server tak vytizeny?

Jsem v pasivnim, port 21. Radsi jsem vypnul SSL, kdyby to melo vliv na rychlost.

Vzdy pri Entering Passive Mode cekam strasne dlouho. U prikazu ls 15s, u put 10s. Na hostingu banan.cz vse jede bleskove.
Pri pouziti grafickeho gFTP to trva stejne dlouho.
