 Re: FTP woes
Hi,
thanks for continuing to look into this! I really appreciate it.
OK, for the Dells: Plain vanilla 1425 with two procs, 4GB RAM each and an additional Dell 2 port GE card.
Concerning the speed: On sending large files, I am quite happy - I can easily send them at +7 MBit, which is probably as fast as I will get to the remote location. My problem is that on sending many small (<1kByte, about 3-5 per s) files with a persistent control connection, I get random packet loss. Usually files transfer in about 0,01s, I have random (about every 100th file) longer delivery times, which can be up to 10s - usually this affects about 5 files until everything quietens down again. Sometimes I do loose the connection alltogether, which then causes a 30s timeout in my delivery software. Alltogether, these random lags lead to queuing of up to ten min., which is completely unacceptable for the app. Behaviour is the same to an internal FTP server (obviously routed through the FW twice), while a direct connection doe not exhibit this. Additional hops (the final conn is from UK to I) make it even worse.
Thanks again,
