# 512M -> 1G -> 3G -> 2G. The store has grown to 2.4 GB (1.2 GB of it range indexes), so 1G
|
|
# covered only ~42% of it. 2G covers nearly all of it; the 2.5 GB of transaction logs are
|
|
# deliberately not counted, Neo4j does not keep them here. Both sizes were measured on a deep
|
|
# refresh of upms: 1G = 552 s, 3G = 519 s, 2G = 517 s. The whole gain is already had at 2G, so
|
|
# the third gigabyte stays with the host (a 4 GB VirtualBox guest runs alongside).
|
|
#
|
|
# The gain is ~6% and modest on purpose to record why: `directio` is false, so Neo4j reads
|
|
# through the OS file cache and the store is cached twice. Block I/O across two whole refresh
|
|
# runs was 237 MB read against a 2.4 GB store — there was never disk I/O to save. A cache miss
|
|
# costs a read() syscall plus a copy, not a seek, and 6% is what removing those is worth. On a
|
|
# host whose file cache could NOT hold the store, the same setting would matter far more — so
|
|
# treat these numbers as this machine's data points, not as a recommendation.
|
|
# Community Edition cannot pre-warm the cache: the first refresh after a restart runs cold
|
|
# (540 s here) and is not a fair measurement.

|
|
# spare GB. This follows the page cache: Neo4j's own rule of thumb is heap + page cache + ~1G, so
