what is a reasonable socket select() wait time?

Question 1:

The API reference for the socket select() wait time parameter says,

"A time to wait of 0 is allowed; this returns immediately with the current
status of the sockets."

What is this "current status" that gets returned?


Question 2:

Will a non-zero select() wait time value slow down an application, if our
actual receive data length is less than our default TCP receive buffer size
SO_RCVBUF (which is 8192 bytes), and our allocated receive data length is
greater than 8192, and no multiplex I/O occurs?
