我正在使用rdb 将我的 rdb 转移到 neo4j 2.0.3 。一开始，我的每个传输查询过去花费的时间非常少，但现在（graphml 文件的大小约为 1.3gbs）插入需要 3-5xtime 并且经常为某些查询抛出此错误。

我通过遍历每行rdb并为电影（如果不存在）及其相关标签（如果不存在）创建节点，然后在它们之间创建关系以及类似的此类操作，将电影数据从rdb导入neo4j。
如何使性能更好并解决此错误？
在搜索时，我登陆了http://docs.neo4j.org/chunked/stable/configuration.html，它提供了详细的性能和配置提示。但一开始似乎很复杂。为了更好的性能，有什么可做和不应该使用neo4j 和 ruby 的。
请帮帮我。
