23.1. System Requirements

Memory constrains graph size, disk I/O constrains read/write performance, as always.

CPU

Performance is generally memory or I/O bound for large graphs, and compute bound for graphs that fit in memory.

Minimum
Intel Core i3
Recommended

Intel Core i7

IBM POWER8

Memory

More memory allows even larger graphs, but needs to be configured properly to avoid larger garbage collection operations. See Section 24.4, “Performance Guide” for suggestions.

Minimum
2GB
Recommended
16—32GB or more

Disk

Aside from capacity, the performance characteristics of the disk are the most important when selecting storage. Neo4j workloads tend significantly toward random reads. Prefer media with low average seek time: SSD over spinning disks. Consult the section called “Disks, RAM and other tips” for more details.

Minimum
10GB SATA
Recommended
SSD w/ SATA

Filesystem

For proper ACID behavior, the filesystem must support flush (fsync, fdatasync). See the section called “Linux filesystem tuning” for a discussion on how to configure the filesystem in Linux for optimal performance.

Minimum
ext4 (or similar)
Recommended
ext4, ZFS

Software

Neo4j requires a Java Virtual Machine to operate. Community Edition installers for Windows and Mac include a JVM for convenience. Other distributions, including all distributions of Neo4j Enterprise Edition, require that the JVM be provided.

Java

OpenJDK 8 (preferred) or 7 or Oracle Java 8 (preferred) or 7

IBM Java 8 (preferred) or 7 (POWER8 only)

Operating Systems

Linux, HP-UX, Windows Server 2012 for production

Additionally, Windows XP and Mac OS X for development

Architectures

x86

OpenPOWER (POWER8, requires IBM Java or OpenJDK, version 7 or 8)

[Important]Important

It is strongly recommended to use an up-to-date Java release as there are issues in early versions of both Java 7 and Java 8 that are known to adversely affect Neo4j.
