我租用了Joyent SmartOS机器来为我的项目托管Neo4j服务器。
该机器是 Extra Small 0.5 GB（1 vCPU），这意味着它有512 MB的RAM。
除了以下默认 neostore。设置外，您会推荐什么？
neostore.nodestore.db.mapped_memory=25M
neostore.relationshipstore.db.mapped_memory=50M
neostore.propertystore.db.mapped_memory=90M
neostore.propertystore.db.strings.mapped_memory=130M
neostore.propertystore.db.arrays.mapped_memory=130M
如果需要，可以使用一些CPU信息：
# psrinfo -pv

配置中的neostore.xxxx.mapped_memory设置应理想地与graph.db目录中相应文件的大小相匹配。
鉴于你有512 MB的RAM可用而且你的图形大约是250 MB，为你提供大约250MB的操作系统和 JVM堆，我觉得它太小了。
如果你的盒子有2G，我会计算：
