### IPV4 specific settings
# turns TCP timestamp support off, default 1, reduces CPU use
net.ipv4.tcp_timestamps = 0
# turn SACK support off, default on
net.ipv4.tcp_sack = 0
# on systems with a VERY fast bus -> memory interface this is the big gainer
# sets min/default/max TCP read buffer, default 4096 87380 174760
net.ipv4.tcp_rmem = 10000000 10000000 10000000
# sets min/pressure/max TCP write buffer, default 4096 16384 131072

# default send socket buffer size, default 65535
net.core.wmem_default = 524287
# maximum amount of option memory buffers, default 10240
net.core.optmem_max = 1048574
# number of unprocessed input packets before kernel starts dropping them, default 300
net.core.netdev_max_backlog = 600000
