Tune Network Stack

Hello everybody… Just wondering if anybody has tweaked their network config to increase buffer memory or suchlike? Experiencing some occasional offline moments which I am guessing may be down to load. I was looking at a couple of generic Linux sites. One says that “The default maximum Linux TCP buffer sizes are way too small”. I see a lot of RX “dropped”:

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
link/ether 00:15:5d:15:70:09 brd ff:ff:ff:ff:ff:ff
RX: bytes packets errors dropped overrun mcast
11229436143248 46109172374 0 116298721 0 8093868697
TX: bytes packets errors dropped carrier collsns
5165612015349 24987253699 0 0 0 0

… which according to another site is “Possibly due to iptables or other filtering rules, more likely due to lack of network buffer memory”.

Very cautious about changing anything, so wondered if anybody else has?

Thanks, Steve
