Gyu-Ho Lee	d97579c399	Add MmapFlags option for MAP_POPULATE (unix) This adds MmapFlags to DB.Options in case we need syscall.MAP_POPULATE flag in Linux 2.6.23+ to do the sequential read-ahead, as discussed in [1]. --- [1]: https://github.com/coreos/etcd/issues/3786	2015-11-08 18:07:10 -08:00
Xiang Li	e67705ed63	do not grow dbsize agressively Only grow the database size when the high watermark increases. We also grows the database size a little bit aggressively to save a few ftruncates. I have tested this on various environments. The performance impact is ignorable with 16MB over allocation. Without over allocation, the performance might decrease 100% when each Tx.Commit needs a new page on a very slow disk (seek time dominates the total write).	2015-11-06 09:39:17 -08:00
