Hi guys,

Whenever the WAN interface is in use (250 down, 20 up) the LAN side of things becomes extremely slow, for instance, when downloading an update (Steam game) and if my wife is watching TV series in the lounge (via kodi with network share to the ClearOS server) kodi needs to keep caching the video playback, every 10 seconds. Any file transfers from ClearOS to a workstation on the network, also, grinds to a halt. (One workstation tested on 100mb switch, another workstation was tested on 1000mb switch)

Could it be my network hardware or is this normal?

Here is the server hardware info, its an HP MicroServer Gen8 with upgraded CPU & Memory:

    It is not normal at all. Have a look at the output of "top" when this is happening. Look for excessive processor usage and low memory. Are you using many power intensive apps (Proxy/Content filter, IDS/IPS, QoS/Bandwidth Manager)

    Hi Nick,

    Sorry for the late reply. Been a busy month! finally got some time to spend back at home.

    This is the output of htop: https://i.imgur.com/nXH4d39.png

    With looking at bandwidth, this is the speeds:

    bwm-ng v0.6.1 (probing every 1.300s), press 'h' for help

    Even killed all services such as Snort, Snortsam, ntopng, etc.

    Any ideas?

    Do you use the proxy/content filter? Probably not from your output of htop. The sort of slowdown you a seeing is not normal. Are you getting any errors on your NIC's. Have a look at the output of "ifconfig".

    I also notice you are using non-ClearOS programs such as OpenVPN with torguard, pihole, redis-server,ddos.sh and I am not sure why suvad is running twice.

    Don't run Proxy or Content filters.

    OpenVPN (Torguard) I've setup with custom IP-routing for some computers. Pihole for my ad blocking and the ddos.sh is DDOS Deflate i was checking out, redis-server is for ntopng, which i forgot to kill.

    Killing all of these still make no difference, sadly.
