asynchronous I/O server

utility is a kernel process which run on an
client machine to service asynchronous I/O requests to its server.
It improves performance but is not required for correct operation.
This program controls the maximum number of processes that the kernel runs.
The options are as follows:
.Bl -tag -width indent
.It Fl n
Specify how many servers are permitted to be started.
A client should run enough daemons to handle its maximum
level of concurrency, typically four to six.
detects that the running kernel does not include
support, it will attempt to load a loadable kernel module containing
.Xr kldload 2 .
If this fails, or no
KLD was available,
exits with an error.
