<body>
<p>Reviews have begun on the CAM I/O scheduler that I wrote
for Netflix. It is anticipated that this process will be done in
time for the &os; 11 branch.</p>
<p>Details about this work can be found in the linked BSDcan
paper from last year.</p>
<p>Briefly, the scheduler allows one to differentiate I/O
types and limit I/O based on the type and characteristics of the
I/Os (including the latency of recent requests relative to
historical averages). This is most useful when tuning system
loads to SSD performance. Both a simple default scheduler, the
same that we use today in &os;, as well as a scheduler that can be
well-tuned for system loads related to video streaming will be
included.</p>
