Cork is a system interface implemented by Linux and some *BSD systems to tell the system that other data are expected to be written to a socket. This allows the system to reduce network fragmentation waiting for network packets to be complete. Using some replay capture and some instrumentation resulted in a bandwith reduction of 11% and a packet reduction of 56%. The tests was done using replay utility so results could be a bit different from real cases as: - replay goes as fast as it can, for instance packets could be merged by the kernel decreasing packet numbers and a bit byte spent (this actually make the following improves worse); - there are fewer channels (no much cursor, sound, etc). The following tests shows count packet and total bytes from server to client using a real network. I used a direct cable connection using 1gb connection and 2 laptops. cork: 537 1582240 cork: 681 1823754 cork: 524 1583287 cork: 538 1582350 no cork: 1329 1834630 no cork: 1290 1829094 no cork: 1289 1830164 no cork: 1317 1833589 no cork: 1320 1835705 Signed-off-by: Frediano Ziglio <fziglio@redhat.com> Acked-by: Christophe Fergeau <cfergeau@redhat.com> |

SPICE: Simple Protocol for Independent Computing Environments
=============================================================
SPICE is a remote display system built for virtual environments which
allows you to view a computing 'desktop' environment not only on the
machine where it is running, but from anywhere on the Internet and
from a wide variety of machine architectures.
Installation
------------
The SPICE package uses GNU autotools, so the build install process
follows the standard process documented in the INSTALL file. As a
quick start you can do
./configure --prefix=/usr --sysconfdir=/etc \
--localstatedir=/var --libdir=/usr/lib
make
sudo make install
Or to install into a private user specific location
./configure --prefix=$HOME/spice
make
make install
The following mandatory dependencies are required in order to
build SPICE
Spice protocol >= 0.12.13
Pixman >= 0.17.7
OpenSSL
libjpeg
zlib
The following optional dependencies increase the available
functionality
Cyrus-SASL
libcacard >= 0.1.2 (Smartcard support)
Opus >= 1.0.0 (Opus audio encoding support)
LZ4 (LZ4 compression support)
GStreamer >= 1.0.0
Communication
-------------
To communicate with the development team, or to post patches
there is a technical mailing list:
http://lists.freedesktop.org/mailman/listinfo/spice-devel
There is also a mailing list for new release announcements:
http://lists.freedesktop.org/archives/spice-announce/
To view known bugs, or report new bugs, in SPICE visit
https://bugs.freedesktop.org/describecomponents.cgi?product=Spice
Bugs found when using an OS distribution's binary packages should
be reported to the OS vendors' own bug tracker first.
The latest SPICE code can be found in GIT at:
https://cgit.freedesktop.org/spice/
