Dedicate some CPU to the task. Create a psrset and bind the ftp daemon to it. If that works then add a few of the read threads as many as what fits in the requirements.

I'm testing an X4500 where we need to send over 600MB/s over the

This is no problem, I get about 700MB/s over a single 10G interface.
Problem is the box also needs to accept incoming data at 100MB/s.
If I do a simple test ftp-ing files into the same filesystem I see
the FTP being limited to about 25-30MB/s.


What was the speed when ftp'ing to /dev/null? (Depending on the exact
Solaris version, ftpd may or may not be really slow)


ftping to a system while  no read load was present maxed out the 1GB
interface at
100MB/s.
Note, the ftp put load was a single stream while the read load were
224 concurrent streams.


How many interfaces did you use and was ftp confined to its own interface?

Outgoing load used a dedicated 10GB interface, incoming load used a dedicated e1000g
interface.
