Pablo, I'm not sure if my experience is relevant for your case, but... as a part of etl job, I needed to process rather large files - a few millions records, with total count of files in low 100. I dynamically grouped them and feed each group to scp job. Since those were plain txt files with tons spaces, I did add compression. disclaimer: that was done on 16 cpu boxes with 64gb memory, so I was all but cpu bound. I did got screamed by sa for saturating the network. But it was easy to adjust by decreasing amount of groups. Hope this helps. Andrew -- Sent from my Android phone with K-9 Mail.

I'm testing use the standar SCP and the PSCP, a command extra from the Puty apps.

And generate and share the RSA public kay is too much work, when some one have to many clients. Any Idea?? -- Pablo Cavero System Engineer +569 8920 9509
