我有带有 Hibernate、Spring、PostgreSQL、MongoDB、Neo4j 和 ElasticSearch 的系统,它与 EhCache 一起用于 Hibernate L2 和 Spring Cache,它运行良好。
我正在测试 Ignite,但是当我将 Ignite 用于 Hibernate L2 时系统变得非常慢(使用 Spring Cache 运行速度很快),我使用 JProfiler 来查看真正慢的地方,我只看到以下方法非常慢:
org.postgresql.core.VisibleBufferedInputStream.read(byte[ ], int, int)
org.postgresql.jdbc2.AbstractJdbc2Statement.parseSql
javax.persistence.EntityManager.find
这对我来说没有多大意义。我正在使用带有https://github.com/apache/ignite/pull/388的 Branch 1.5.1-2 中的 Ignite 1.5.1.final-SNAPSHOT (我进行了更改以自动为 Hibernate L2 创建缓存),我用 1.4.0 测试过,问题是一样的。
