What's new? cFosSpeed
* New feature
! Software change requires modification of your configuration
- Information only
Revision history: ---------------------------------------------------------
cFosSpeed 10.50 build 2338 -- 21-Mar-2019
* In the Prioritize Programs dialog you can now select to display the used
programs only (instead of all programs).
* settings.ini and thereby the list of default program priorities is now
updated automatically. If you don't want this, delete the key named
'version' in the section [All] at the end of the file.
There is an option in the program update menu to enable / disable this
* Install and uninstall now also clean the driver store from cFosSpeed
INF files. If an install is still unsuccessful or results in
"driver not loaded" problems, you can run the installation, ignore
errors and then run a deinstall. This should clean the driver store from
old cFosSpeed INF files.
* cFosSpeed now tracks the host name from HTTP, TLS and QUIC conenctions.
It can be displayed with "spd cons -host". This will print the host name
instead of the remote address. If you want both, use "-host2" or
"-host -remote" instead.
This new feature is also available in the "current connections (advanced)"
* Advanced connection overview (and "spd cons" as well) now only keeps one
UDP pseudo-connection per DNS server. This prevents a load of UDP DNS
pseudo-connections that were just used for one DNS query.
* Added installer checkbox to allow us to occasionally (max. once a year!)
collect some anonymous meta data from your connections (we clear out your IP
address). This is to help us develop a new and improved form of traffic
class detection. Please switch it on, we need real live traffic data to
develop this new feature.
For a detailed list of collected data, see http://www.cfos.de/collected-data.txt
* click-through now has its own sub-menu. You can now chose between "off",
"click-through" (always) and "click-through (auto)". In auto mode, the
window will change to click-opaque mode if you hover with your mouse cursor
over it for 4 seconds (and will revert back to click-through mode if the
cursor is not in the window for 4 seconds). So, if the skin window
prevents you from interacting with other windows, you can use the click-
through mode. Thanks to Death_Master for the suggestion.
+ The list of used programs is now updated periodically and not only when
the usage graph is opened.
+ Status window positions are now stored per network adapter, regardless of
router MAC. This should eliminate confusion when the network adapter is
used with different routers.
+ Improved usability of the context menu.
+ Advanced connection overview (and "spd cons" as well) is now by default
sorted by protocol (first TCP, then UDP), then by local IP address:port,
then remote. IPv4 is sorted in front of IPv6.
+ Added more games and other programs to the program prioritization UI.
+ Fixed and improved sorting in advanced connection overview: column "class"
is now ordered by prio, "prot" by protocol/local/remote and the columns
have a default order that makes sense (i.e., the most important at the top
+ The entries in the current connections dialog are now sorted according to
+ Skin window position is now stored relative to the nearest corner of the
current monitor. Thereby the position is always fixed relative to that
corner if you change monitor resolution.
+ cFosSpeed now tracks DUPACKs to be able to assess connection quality.
"spd ns" has now a row with "Duplicate ACKs".
+ "spd cons" has now rows for tx'ed DUPACKs (an indicator for receive quality)
and tx resends (an indicator for transmit quality).
+ "spd cons" now accepts a "-head:<n>" parameter to only print the first
+ Optimized amount of in-flight data that cFosSpeed allows (sort of a global
RWIN) for lower ping times. This should lower your ping times by about
30 msec if your are transferring data at the same time.
+ If low latency mode is switched on and non-cooperative mode is selected,
cFosSpeed will act as if in cooperative mode, that is, we're trading
high bandwidth for low ping time.
+ cFosSpeed's foreground window detection will automaticall grant high prio
to data from the current foreground process (as long as it's in the
foreground). This could lead to the case where you upload/download and
all that data is set to high, effectively congesting the whole line, even
for small high-prio data (like DNS or VoIP).
This is now fixed: only non-bulk data from foreground processes is set to
high and bulk data is now elevated to normal. That's still better than low,
which is where is would normally go.
+ cFosSpeed version and build numbers are saved to registry to
+ When using "spd tcb" command you can now add a wildcard to specify which
connection to display, like "spd tcb 8.*:80" or "spd tcb 8.*:*".
+ Added new TCP counter in "spd netstat": Data segments. This will only be
increased if the segment contains any data (i.e. is non ACK-only). It now
allows for a more accurate calculation of resent percentage.
+ Added support for Windows 10 version 1803, a.k.a. Spring Creators Update,
a.k.a. Redstone 4.
+ Added L7 detection of certain QUIC packets.
+ Improved evaluation of the User-Agent string for the L7 protocol detection.
+ The L7 protocol data field now contains the HTTP Host header field in
addition to the Content-Type.
+ Improved "spd ports" display.
x Fixed multiple bugs where the status window didn't re-open after hibernate/
x Fixed a bug where auto-hide on fullscreen hid the status window even if the
fullscreen window was on a different monitor.
x Fixed a bug in the update of used programs.
x Actions on buttons in skin windows were disabled. Fixed.
x Fixed a bug where the program list in the add new program dialog was not
updated correctly. Thanks to Tim M for reporting it.
x Fixed a very old bug that could lead to a bluescreen in rare circumstances.
Thanks to Philippe Bertrand for dump file.
x Fixed a possible deadlock (freeze).
x Improved dumping speed.
x Clicking on the status windows turned off auto-arrange. Pressing ESC while
moving the window did not restore it to the original position. Fixed,
thanks to Kikka.
x Fixed an old bug that could have lead to erroneous detection or rejection
of RST segments in cFosSpeed.
x Fixed constant deletion/creation and trace writing if VM virtual adapter
switched his MAC adress on and off constantly.
x Fixed a spurious problem with opening the browser. Thanks to Stefan
Waldmann for bug report.
x Fixed detection of IPv6 address of router.
x When using "spd cons" or the advanced connection overview, the sorting will
now sort TCP and UDP connections together.
x Fixed detecion of UDP protocols.
- Removed old, long unused code. Removed filter rules -ppp, -mp-header,
-mp-begin, -mp-end, -mp-frag, -pppp that were always false anyway (since
cFosSpeed would never get PPP frames).
- Internal modernization of interlocked variables.
- Tested with Windows 10 Octover 2018 Update, version 1809, codename
- New SDK used. This includes mitigation against certain Spectre attacks.
- Added / corrected several games in prioritization list. Thanks to Sc3ed.
- Added some trace output to find a problem where LAN ports will open and
close with a frequency of about 10 seconds. If this still happens to you,
please contact us!
- Switched to new compiler.
- Traffic Shaping setting is now by default "not cooperative" owing to the
fact that usually there are other non-cFosSpeed clients on the LAN as well
(smartphones, consoles, etc.)
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。那么它能做什么呢？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。
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。
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。
