【軟體】網路頻寬最佳化程式 : TCP/IP Optimizer

[url]http://www.speedguide.net/[/url] 出了一支小程式 : TCP/IP Optimizer

檔案下載:
[url]http://www.speedguide.net/files/TCPOptimizer.exe[/url]

使用上很方便 , 只要選擇上網方式 ADSL / PPPoE / CABLE 然後選最下方 Optimal Settings 再按 Apply Changes 自動重新開機後即會自動調整您網路卡的 TCP/IP 最佳設定

建議各位使用前 / 使用後可以到這個網址測試看看 [url]http://forums.speedguide.net:8117/[/url] 並記錄數值後上來回報互相討論一下

[color=red]測試前原本把數據貼在文件檔上的...

修改完馬上重開機 @@"...所以只有使用後的數據

有點印象說, Time to live left = 53 hops(原本是117 hops)[/color]

TCP options string = 020405b40103030201010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 64240
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 53 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

用完這個更新, 開網頁的速度沒話說...
不過下載東西常常一半逾時...ping東森兩台DNS跟華信的都...

ㄚ土伯伯~*
能教我怎麼還原嗎~
因為......用了之後
網路掛掉了啦QQ"
只剩微軟跟PCZONE能開的起來 (其他不想試了..連奇摩都開不起來~"~)
才剛重新安裝OS
還沒GHOST!!
我不要再重灌了/________\

PS:我的OS是"WIN98SE"

沒那麼嚴重吧....

還原之前的設定 :

FILE -> Restore Backuped Up Settings 並重開機

請問，透過分享器上網的是不是不適用呢？

一些參數設定都是記錄在分享器裡面，琥珀想，除非連分享器的設定一併調整，否則這方法可能會有問題？

來不及了@@
已經重灌OS好了
是我裝分享器的問題嗎?
等待解答中~*

TCP options string = 0204052801010101

MTU = 1360
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.

MSS = 1320
Maximum useful data in each packet = 1320, which equals MSS.
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65535
Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
506880 (MSS x 48 * scale factor of 8)
253440 (MSS x 48 * scale factor of 4)
126720 (MSS x 48 * scale factor of 2)
63360 (MSS x 48)

bandwidth * delay product:
Your RcvWindow limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 52 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = OFF

IP type of service field (RFC1349)= 00000000

me too犯了同樣的錯！一按完自動開機...真慘！
所以沒前面的數字！
但有明顯的變快！
而前面有人覺得在ip分享器後面有問題！
結論是！沒有！至少我沒有！
但可以確定的是有變快！^^

忘了補充！
阿土喔∼
你教的那個是他在"動作前"有做備份的動作吧？
程式又沒自動幫忙做！
所以重灌應是最後一個辦法了！
雖然我跟他同樣的是win98se而且在ip分享器後...^^

[QUOTE][i]最初由 gadam 發表[/i]
[B]在Speedguide那裡有關MTU的設定大多是建議1492
在speedguide有教如何測最大mtu [/B][/QUOTE]
　　應該說 PPPoE 的 Max 是 1492，一般 EtherNet 是 1500，不過實際上會因為中間的網路設備差異而需要調整 MTU 值。
