Figured it out. The Linux kernel has the following TCP/Net options. The values are what I came up with for my system. If you want to change these make sure to do your homework and find values which are optimal to your system and Internet connection.
net.core.rmem_default = 256960 net.core.rmem_max = 16777216 net.core.wmem_default = 235116 net.core.wmem_max = 16777216 net.ipv4.tcp_rmem = 5120 256960 16777216 net.ipv4.tcp_wmem = 5120 235116 16777216
*wmem_* send memory space
I added these to /etc/sysctl.conf and executed
When I was testing I executed
sysctl -w option=value
ifconfig -v eth0 mtu 1492 txqueuelen 1024
txqueuelen is the length of the transmit queue, increasing this relieves congestion--if you have a slow connection set this to a lower value.
