typedef prevector<28, uint8_t> CScriptBase |
We use a prevector for the script to reduce the considerable memory overhead of vectors in cases where they normally contain a small number of small elements.
Tests in October 2015 showed use of this reduced dbcache memory usage by 23% and made an initial sync 13% faster.
