We are trying the sftp to solve the problem. With sftp you can configure the buffer (in bytes) so it does not make one conection per file (instead the 100 conection with scp) but one only conection for the whole transfer, the performance look good. I´ll put the new script in production and we will see... Regards, Horacio. ------------- Hi, I am using scp to copy large amount of small files between 2 servers with a firewall in the middle, but the copy takes all CPU, this is the situation: - The files are copied in batch of 100 tif images, in a directory with more than 5 million files. - the server that initiate the scp is a 1.2Ghz P3 with 2G in ram, the receiver is a double Xeon 2.6ghz with 2G in ram. The first server takes no time to send the file, but the receiver takes more than 200segs to copy. They are in a 100mb lan. - the top comand shows 98% free cpu before the scp, when scp start it takes 100% of the 2 xeon cpu. The problem is not the ram, both servers have more than 1G free when scp starts. I tried with all the SCP flags (-q, -c blowfish, etc), and nothing works.... Regards, Horacio Reyes Rios Eng.
