Gregory Burd	1d6dfee192	Cache sizing is critical for performance. This change guesses at a reasonable setting for the WiredTiger cache size at runtime. This cache is shared across all vnodes regarless of how many are active at any given time. The algorithm is: max(1GB, 1/3 (RAM - Beam RSS size)). We don't enable direct_io on purpose and data will be double buffered in WiredTiger's cache and the filesystem buffer cache. This turns out to be faster than direct I/O despite wasting a bit of RAM.	2013-03-14 13:27:59 -04:00

Cache sizing is critical for performance. This change guesses at a

reasonable setting for the WiredTiger cache size at runtime.  This cache
is shared across all vnodes regarless of how many are active at any
given time.  The algorithm is: max(1GB, 1/3 (RAM - Beam RSS size)). We don't
enable direct_io on purpose and data will be double buffered in WiredTiger's
cache and the filesystem buffer cache.  This turns out to be faster than
direct I/O despite wasting a bit of RAM.

add temp copy of riak_kv_backend

Add a temporary copy of riak_kv_backend, renamed to
temp_riak_kv_backend, to allow wterl to build on its own. This file
must be deleted when riak_kv_wterl_backend is moved to its proper
place in riak_kv.
