Version 1.20

Item posted by Sergey Poznyakoff <gray> on Thu Jun 17 11:06:19 2021.

Version 1.20 is available for download.

Changes in this version:

New bucket cache

The bucket cache support has been rewritten from scratch. The new code provides for significant speed up of search operations.

Change in the mmap prereading strategy

Pre-reading of the memory mapper regions, introduced in version 1.19 can be advantageous only when doing intensive look-ups on a read-only
database. It degrades performance otherwise, especially if doing multiple inserts. Therefore, this version introduces a new flag
to gdbm_open: GDBM_PREREAD. When given, it enables pre-reading of memory mapped regions. (details)
