The new code is a bit slower for very small numbers of writes, but scales linearly as the number of writes increases. The old code scaled as O(N^2) with the number of writes, making it unusable for large N. After testing, this needs to be merged into the Samba version of tdb, along with many of the other recent tdb changes in the ctdb tree. modified: lib/tdb/common/transaction.c transaction.c-20070220022425-m1wibgjq7n5hahs6-11
