rsync running slow?

Today I was transferring files through rsync it was taking forever, my guess was the new server or old server was out of memory so I killed some procs and even rebooting the server but still it was crawling. So I thought I would think out of the box and after a couple trial and errors I tried a nic reboot and wow it was super fast from there.

/etc/init.d/network restart

I’m still not sure how the nic got blogged up but this worked like charm.

Keep in mind this is a temp fix, what you need to do is both your nic card going by adding another IP via cpanel and via the setup tool access from the root of the server. Try to separate the IP traffic that best that you can between both nic cards on the server.
