lightweight objects in the linux kernel that enable users
to partition their multiprocessor machine.
Multiprocessing is the use of two or more central
processing units (CPUs) within a single computer system
source : http://en.wikipedia.org/wiki/Multiprocessing
-j [jobs], --jobs[=jobs]
Specifies the number of jobs (commands) to run
simultaneously. If there is more than one -j option, the
last one is effective. If the -j option is given without
an argument, make will not limit the number of jobs that
can run simultaneously.
machines with multiple processors can attach network
programs of higher priorities to a processor that is
little consumed or idle.
Acetic acid, CH3COOH, also known as ethanoic acid, is an
organic acid that gives vinegar its sour taste and
pungent smell. It is a weak acid, in that it is only a
partially dissociated acid in an aqueous solution.

Try to send full-sized packets during retransmit.
This is enabled by default.
TCP smart Framing, or TCP-SF for short, enables the Fast
Retransmit/Recovery algorithms even when the congestion
window is small. Without modifying the TCP congestion
control based on the
TCP-SF adopts a novel segmentation algorithm: while
Classic TCP always tries to send full-sized segments, a
TCP-SF source adopts a more flexible s segmentation
algorithm to try and always have a number of in flight s
segments larger than 3 so as to enable Fast Recovery. We
motivate this choice by real traffic c measurements,
which indicate that today's traffic is is populated by
short-li flows, whose only means to recover from a packet
loss is by triggering a Retransmission Timeout. The key
idea of TCP-SF can be imple- mented on top of any TCP
flavor, , from Tahoe to SACK, and re- quires
modifications s to the server TCP stack only, and can be
easily coupled with recent TCP enhancements. The
performance of the proposed TCP modification were studied
by means of simulations, live measurements and an ana-
lytical model. In addition, the analytical model we have
devised has a general scope, making it a valid tool for
TCP performance evaluation in the small window region.
Improvements are remark- able under several buffer
management schemes, and maximized by byte-oriented
