== PostgreSQL Weekly News - January 29 2006 == Stephan Vollmer reported low GiST indexing performance with tsearch2. Tom Lane and Martijn van Oosterhout investigated and after some discussion on the performance list they identified a bit counting function as the culprit. Tom committed an alternative implementation using a static lookup table to various contrib modules (intarray, ltree, trgm and tsearch2) that resulted in a 20x performance improvement for large indexes. Discussion about further improving the so called "picksplit" algorithm for another 10x gain ensued but did not reach a conclusive resolution, at least not for the 8.1 branch.
