I am trying to use Iperf3 but there is an error "iperf3: error - unable to connect to server: Connection refused"
My ClearOS firewall is off and my laptop firewall is also off.
Do I need to install iperf3 on my ClearOS server? if so how can I do that?

Yes you need to install it:
If your are new to ClearOS, please check if you have an RTL8111/8168/8411 NIC with:
Yes you need to install it:
yum install iperf3
If your are new to ClearOS, please check if you have an RTL8111/8168/8411 NIC with:
lspci -k | grep Eth -A 3
If you do, don't bother speed testing until you install the better drivers:yum install kmod-r816*
Then reboot. Responses (8)

Just a simple:
will work, or:yum remove kmod-r816*
Be very careful when removing apps with yum. If the command tries to remove a load of dependencies which don't obviously belong to the apps you want to remove, stop. You can bring your system to its knees. In this case, it won't remove any dependencies.yum remove kmod-r8168 kmod-r8169

No. The r8169 is supposed to cover all cards including RTL8169 cards but it does not perform well the an RTL8168 card. The r8169 driver comes in the kernel. The r8168 is supplied by RTL, but for some reason, never gets incorporated in the kernel. The RTL8169 chip is PIC and the RTL818 is PCI-E.
To revert, uninstall both the kmod-r8168 and kmod-r8169 drivers and reboot.
I see.
Is this the right command for that? "yum remove kmod-r8168" and "yum remove kmod-r8169" -
