简而言之，这世界上没有免费的午餐，任何软件都不可能帮你提升物理带宽！cFosSpeed 也不例外。那么他能做什么呢？
cFosSpeed是一款软件 QoS ，也就是流量整形软件，可以帮助那些在疯狂下载的同时也能保证相对流畅的阅读网页体验以及在线游戏。这对于我国大面积使用的不对称线路，有非常好的效果。
cFosSpeed 有什么优点？
相比一般那些只是单纯地改改系统参数就敢打着网络优化软件的旗号，让我们仔细看看cFosSpeed的几大独特之处：
1. 支持多种宽带接入方式，系统底层程序，占用内存小

2. 独有的 Traffic Shaping 传输方式，全速上传时亦能改善网络响应
Traffic Shaping 几乎不需要你进行任何设置，它会自我学习，至于如何让软件更快进入状态。

3. 多人多电脑同时上网的速度协同优化，上网下载两不误
cFosSpeed 可以让同一路由器下的多台PC通过软件自动协同达到整体最佳网络体验。打一个比方，一个宿舍的小A和小B用同一个路由器上网。如果小A在用在进行满速下载，小B在浏览网页，该软件会自动降低小A电脑迅雷的通信优先度（并不是限速！）以保证小B的流畅上网。

4. 有效减少网络延迟，更低的PING值令你在网络竞技游戏中尽情厮杀
Traffic Shaping 技术已经可以有效减少传输数据时对网络延时的影响，如果你希望在游戏中能获得更小的ping，先右键托盘区的软件图标，再按下图所示进行选择。当选择优化ping时间时，软件会稍稍牺牲一些带宽来缩短ping时间。

更新日志（概要）：
cFosSpeed 10.12 build 2262 -- 05-Apr-2016
! Removed support for Windows XP and Windows Vista.  Now, the minimum
  supported operating system is Windows 7.  If you require cFosSpeed for
  Windows XP or Vista, you can download version 10.10.2238 from
  http://www.cfos.de/cfosspeed-xp-vista-v1010.exe
+ Added a lot of games and other programs to the list of prioritized
  programs. Thanks to Armor Darks for carefully checking the .exe files.
+ cFosSpeed may now remove more expired DNS names from the refresh list.
+ New experimental feature: setting "spd gset patch_dns_ttl XXX" enforces
  a minimum DNS TTL of <XXX> seconds.  This may be useful to prevent constant
  DNS refreshes of names with very low TTLs.
+ cFosSpeed can now distinguish between used and unused domains for the DNS
  refresh feature.
x Fixed problems with Driver Verifier under Windows 8 and up.  Thanks to
  Raymond Karlsen for the bug report.
x Fixed IPV6 DNS detection.
x Used new SHA256 code signing certificate.  This should prevent the erroneous
  SmartScreen warning when installing the downloaded distribution from the web.
x One more fix for a degenerate case in IPv6 packet handling.
x Tried to fix an IPv6 problem where local traffic is not detected as such
  and erroneously shaped.  Thanks Ingo Asche for testing.
x Fixed IPv6 address detection problem when ping_dest was specified only for
  IPv4.  This also caused spd.exe to use up a lot of CPU time.  Thanks to
  Andrey Chernov for bug report and testing.
x Fixed bugs in IPv6 address detection and improved trace output.
x Fixed a bug in setup.
x Fixed mouse handling of tray icons for Windows 10.
x Fixed a bug in selecting the shared network connection for WiFi access point.
x Fixed display of full line speed in some rare cases.
x Ignore more UPnP bogus bitrates.
- Added trace output and handling for possible spd.exe full throttle problem.
- Restored DNS cache refresh dialog option.  DNS cache refresh is now on by
  default.
- Switched to new Visual Studio 2015 compiler and Windows 10 SDK/WDK.
- Switched off TCP checksumming in cFosSpeed.  If you desire, you can switch
  it back on by using "spd gset checksum_tcp 1 -save", but it is quite
  time consuming and its use is marginal.
