コピペしてみるよ。
・・・MacOS9のまま速度を出そうと頑張ってみたけど
あとはOS替えるしかないかなぁ、と思ってます・・・

Notes: Read the Analyzer FAQ if the above is not your IP address.
TCP options string = 0204058603030001
MTU = 1454
MTU sometimes used in PPPoA applications. If not, consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.
MSS = 1414
Maximum useful data in each packet = 1414, which equals MSS.
Default TCP Receive Window (RWIN) = 32768
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 32768

For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:
520352 (MSS x 46 * scale factor of 8)
260176 (MSS x 46 * scale factor of 4)
130088 (MSS x 46 * scale factor of 2)
ﾊ65044 (MSS x 46)

bandwidth * delay product (Note this is not a speed test):
Your TCP Window limits you to: 1310.72 kbps (163.84 KBytes/s) @ 200ms
Your TCP Window limits you to: 524.288 kbps (65.536 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 242 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = OFF
IP type of service field (RFC1349) = 00000000 (0)
