a4e28b3 Set TCP_NODELAY on P2P sockets. (Gregory Maxwell)
2015-10-22Set TCP_NODELAY on P2P sockets.Gregory Maxwell
Nagle appears to be a significant contributor to latency now that the static sleeps are gone. Most of our messages are relatively large compared to IP + TCP so I do not expect this to create enormous overhead. This may also reduce traffic burstyness somewhat.

2015-10-13Drop minRelayTxFee to 1000Matt Corallo
There is no exact science to setting this parameter, but 5000 (just over 1 US cent at the time of writing) is higher than the cost to relay a transaction around the network (the new benchmark due to mempool limiting).

2015-10-13Implement on-the-fly mempool size limitation.Matt Corallo
After each transaction which is added to mempool, we first call Expire() to remove old transactions, then throwing away the lowest-feerate transactions. After throwing away transactions by feerate, we set the minimum relay fee to the maximum fee transaction-and-dependant-set we removed, plus the default minimum relay fee. After the next block is received, the minimum relay fee is allowed to decrease exponentially. Its halflife defaults to 12 hours, but is decreased to 6 hours if the mempool is smaller than half its maximum size, and 3 hours if the mempool is smaller than a quarter its maximum size. The minimum -maxmempool size is 40*-limitdescendantsize, as it is easy for an attacker to play games with the cheapest -limitdescendantsize transactions. -maxmempool defaults to 300MB. This disables high-priority transaction relay when the min relay fee adjustment is >0 (ie when the mempool is full). When the relay fee adjustment drops below the default minimum relay fee / 2 it is set to 0 (re-enabling priority-based free relay).

2015-10-09Bump minrelaytxfee defaultWladimir J. van der Laan
To bridge the time until a dynamic method for determining this fee is merged. This is especially aimed at the stable releases (0.10, 0.11) because full mempool limiting, as will be in 0.12, is too invasive and risky to backport.
