-Latency is how long something takes to happen, so obviously
the shorter this is
the better
. The Low Latency patches ([IIRC]) go through
the kernel and find a lot
of the times where the kernel is busy doing something for a long time and let other processes run. This is important so that sound doesn't skip
.
+Latency is the delay between an event and
the reaction to it
. It is usually desirable for latency to be low, though low latency usually comes at
the cost
of throughput, which is
the rate at which events can be reacted to
.
-In networking, ping(8) is often the
utility used to check latency
. You often hear gamers talking about "ping times"
and wanting them to be very
low, or more importantly
for them not to change
(which is called
[Jitter
])
+In networking, latency is usually expressed in terms of "ping time", measured using the
ping(8) utility. Consistent
and low latency is important
for network games and voice chat
(see
[VoIP
]) applications.
+
+The Low Latency patches for the [Linux] [Kernel] reduce the duration of many uninterruptible sequences, so other processes can run, preventing f.ex sound from skipping.
