ip_squeue_worker_wait<br />
Description<br />
Default<br />
Range<br />
Dynamic?<br />
When to Change<br />
Governs the maximum delay in waking up a worker thread to<br />
process TCP/IP packets that are enqueued on an squeue. An<br />
squeue is a serialization queue that is used by the TCP/IP<br />
kernel code to process TCP/IP packets.<br />
10 milliseconds<br />
0 – 50 milliseconds<br />
Yes<br />
Consider tuning this parameter if latency is an issue, and<br />
network traffic is light. For example, if the machine serves<br />
mostly interactive network traffic.<br />
The default value usually works best on a network file server,<br />
a web server, or any server that has substantial network traffic.<br />

ip_squeue_write<br />
Description<br />
Default 2<br />
Range 0 to 2<br />
Governs the behavior of squeue operations while processing<br />
TCP/IP packets coming from the application.<br />
A value of 1 causes the running thread to process the current<br />
packet only. A value of 2 causes the running thread to process<br />
all packets that are queued on the squeue.<br />
Dynamic?<br />
Yes<br />
