The default window is limited to the maximum\nof 10*1460 and 2*mss (when mss \u003e 1460).\n\ndraft-ietf-tcpm-initcwnd-00 is a proposal to the IETF that recommends\nincreasing TCP\u0027s initial congestion window to 10 mss or about 15KB.\nLeading up to this proposal were several large-scale live Internet\nexperiments with an initial congestion window of 10 mss (IW10), where\nwe showed that the average latency of HTTP responses improved by\napproximately 10%. This was accompanied by a slight increase in\nretransmission rate (0.5%), most of which is coming from applications\nopening multiple simultaneous connections. To understand the extreme\nworst case scenarios, and fairness issues (IW10 versus IW3), we further\nconducted controlled testbed experiments. We came away finding minimal\nnegative impact even under low link bandwidths (dial-ups) and small\nbuffers. These results are extremely encouraging to adopting IW10.\n\nHowever, an initial congestion window of 10 mss is useless unless a TCP\nreceiver advertises an initial receive window of at least 10 mss.\nFortunately, in the large-scale Internet experiments we found that most\nwidely used operating systems advertised large initial receive windows\nof 64KB, allowing us to experiment with a wide range of initial\ncongestion windows. Linux systems were among the few exceptions that\nadvertised a small receive window of 6KB. The purpose of this patch is\nto fix this shortcoming.\n\nReferences:\n1.

At each read operation, a seek is done to find the\nlast socket that was previously read. This seek operation requires\nthat the sockets in the table need to be counted up to the current\nfile position, and to count each of these requires taking a lock for\neach non-empty bucket. The whole algorithm is O(n^2).\n\nThe fix is to cache the last bucket value, offset within the bucket,\nand the file position returned by the last read operation. On the\nnext sequential read, the bucket and offset are used to find the\nlast read socket immediately without needing ot scan the previous\nbuckets the table. This algorithm t read the whole table is O(n).\n\nThe improvement offered by this patch is easily show by performing\ncat\u0027ing /proc/net/tcp on a machine with a lot of connections. With\nabout 182K connections in the table, I see the following:\n\n- Without patch\ntime cat /proc/net/tcp \u003e /dev/null\n\nreal\t1m56.729s\nuser\t0m0.214s\nsys\t1m56.344s\n\n- With patch\ntime cat /proc/net/tcp \u003e /dev/null\n\nreal\t0m0.894s\nuser\t0m0.290s\nsys\t0m0.594s\n\nSigned-off-by: Tom Herbert \u003ctherbert@google.com\u003e\nAcked-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nSigned-off-by: David S.

This leads to wrong\ndecisions in retransmits_timed_out() if tcp_time_stamp is larger than\nthe specified timeout, which is very likely.\nIn this case, the TCP connection dies after the first attempted\n(and unsuccessful) retransmission.\n\nWith this patch, tcp_skb_cb-\u003ewhen is used instead, when retrans_stamp\nis not available.\n\nThis bug has been introduced together with retransmits_timed_out() in\n2.6.32, as the number of retransmissions has been used for timeout\ndecisions before.
