Net.core.rmem_default = 4194304

Net.core.rmem_max = 4194304

Net.core.wmem_default = 262144

Net.core.wmem_max = 1048576

Net.ipv4.ipfrag_high_thresh = 524288

Net.ipv4.ipfrag_low_thresh = 393216

Net.ipv4.tcp_rmem = 4096 524288 16777216

Net.ipv4.tcp_timestamps = 0

Net.ipv4.tcp_sack = 0

Net.ipv4.tcp_window_scaling = 1

Net.core.optmem_max = 524287

Net.core.netdev_max_backlog = 2500

Net.ipv4.tcp_mem = 16384 16384 16384

Fs.file-max = 6815744

Fs.aio-max-nr = 1048576
