I've found FTP times are determined by many factors, chief of which is
how you are connected.
LPAR's using Virtual Ethernet or Virtual OptiConnect (or "real"
OptiConnect, for that matter) will outperform those going over a LAN,
usually.
I've also found that on 8xx boxes, Virtual OptiConnect outperforms
Virtual Ethernet, but the opposite is true on i5's.
In either case, the system processing and memory load can affect
transfers as well.
In my own tests on i5, for instance, I got an effective rate (that is
actual data across the pipe - meaning effective rate of 1Mb/s would mean
a 1Mb (Mbits, so about 125MB) file took 1 second to FTP) of about
500Mb/s for Virtual Ethernet (using the jumbo frame size of 8996) and
about 400 Mb/s for Virtual OptiConnect. Virtual Ethernet with the
default frame size of 1496 was a bit over 300Mb/s.
So at the fastest of those rates, a 35GB file (a.k.a. 286720 M bits)
would take about 9 hours to FTP (if my math is right!).

Can you give me a time estimate on how long those large files took to
ftp?

I sent bigger files between the systems.

OK... i'll bump this one, maybe I caught people at lunch.
Is a 35gb file FTP'd between 2 iSeries boxes an outlandish proposition?
