Heap boundaries of Neo4J

Hello everyone,

I am trying to measure the heap boundaries of Neo4J. I need to find the beginning/end address of the page cache. I need to find out, how Neo4j allocates the page cache.
I am running LDBC benchmark suite with SF100 (100GB) on neo4j-community-3.5.4-SNAPSHOT using 120gb pagecache size and 180gb heap-size.

My system specs are:

Architecture:          x86_64
CPU op-mode(s):        32-bit, 64-bit
Byte Order:            Little Endian
CPU(s):                16
On-line CPU(s) list:   0-15
Thread(s) per core:    1
Core(s) per socket:    8
Socket(s):             2
NUMA node(s):          2
Vendor ID:             GenuineIntel
CPU family:            6
Model:                 45
Model name:            Intel(R) Xeon(R) CPU E5-2690 0 @ 2.90GHz
Stepping:              7
CPU MHz:               1200.083
CPU max MHz:           2901.0000
CPU min MHz:           1200.0000
BogoMIPS:              5801.18
Virtualisation:        VT-x
L1d cache:             32K
L1i cache:             32K
L2 cache:              256K
L3 cache:              20480K
NUMA node0 CPU(s):     0,2,4,6,8,10,12,14
NUMA node1 CPU(s):     1,3,5,7,9,11,13,15

Could you please let me know how to find the above?
Thank you

Is this a research project?

If you want to benchmark you should def. use the latest (4.1.2 tomorrow) version of enterprise-edition.

And make sure to follow Cypher Tuning recommendations.


i am working on an altered version of mine on 3.54 version. I need to stick to that unfortunately!
