Dave Collins	497aac6d4a	Add new funcs to allow size hints on getdata/inv. ... This commit adds two new functions named NewMsgGetDataSizeHint and NewMsgInvSizeHint. These are intended to allow callers which know in advance how large the inventory lists will grow the ability to provides that information when creating the message. This in turn provides a mechanism to avoid the need to perform several grow operations of the backing array when adding large number of inventory vectors.	2014-01-08 17:21:51 -06:00
Dave Collins	5f971e10e6	Pre-allocate space for slices. ... Several of the messages store the parts that have a variable number of elements as slices. This commit modifies the code to choose sane defaults for the backing arrays for the slices so when the entries are actually appended, a lot of the overhead of growing the backing arrays and copying the data multiple times is avoided. Along the same lines, when decoding messages, the actual size is known and now is pre-allocated instead of dynamically growing the backing array thereby avoiding some overhead.	2013-09-25 14:38:28 -05:00
