system call
Trying to figure out a load issue with a webserver. I have traced a php script and noticed the following

Code:
connect(4, {sa_family=AF_INET, sin_port=htons(3306), sin_addr=inet_addr("XX.XX.XX.XX")}, 16) = -1 EINPROGRESS (Operation now in progress) <0.000035>
poll([{fd=4, events=POLLIN|POLLOUT|POLLERR|POLLHUP}], 1, 2000) = 1 ([{fd=4, revents=POLLOUT}]) <0.000120>
getsockopt(4, SOL_SOCKET, SO_ERROR, [8589934592], [4]) = 0 <0.000006>
fcntl(4, F_SETFL, O_RDWR)               = 0 <0.000005>
setsockopt(4, SOL_TCP, TCP_NODELAY, [1], 4) = 0 <0.000006>
poll([{fd=4, events=POLLIN|POLLERR|POLLHUP}], 1, 1471228928) = 1 ([{fd=4, revents=POLLIN}]) <1.122287>



Looks like a connection to db server in same LAN taking time.

It looks like poll takes more than 1 sec. Is this a network issue?
