#10 Slow transfer rate for large files

[Jim Faut]

Using JSCH to scp a large file (100 MB+) is
extremely slow. A transfer takes several minutes
even on a local network. Transferring the same file
using the command line scp command takes only 30
seconds.

I am calling jsch from Ant 1.6.

I am using the command line scp command using
Solaris.

Try to change buffer sizes in scpTo and scpFrom to a higher
value. It works fine for me.
