I just ran this:

Web100 reports the Round trip time = 370.75 msec; the Packet size = 1460 Bytes; and
No packet loss was observed.
C2S throughput test: Packet queuing detected: 1.18%
S2C throughput test: Packet queuing detected: 5.41%
This connection is receiver limited 91.43% of the time.
Increasing the the client's receive buffer (62.0 KB) will improve performance

Server 'nitro.ucsc.edu' is not behind a firewall. [Connection to the ephemeral port was successful]
Client is probably behind a firewall. [Connection to the ephemeral port failed]
Packet size is preserved End-to-End
Server IP addresses are preserved End-to-End



Is the part in red something I can improve on?

Post your TCP analyzer report.

EDIT: Found it in another thread, you could try setting your RWIN to 128480
