The performance is over的意思|示意

The terrible performance of the Japanese equity market over the past 20 years is well known. It is easy to forget that property prices have suffered almost as much.

过去20年间日本股市的糟糕表现令人刻骨铭心，然而却极易忘却其地产价格同样深受其苦。

ObjectSpace is a feature that allows to iterate over objects in the heap using Ruby code. This feature has been causing performance problems for JRuby for some time.

ObjectSpace是一种允许使用Ruby代码在栈中遍历所有对象的特性，这一特性给JRuby造成的性能问题已经存在一段时间了。

Performance, on the other hand, is subject to change over time as the actual implementation code is modified.

另一方面，随着实际实现代码的修改，性能总在发生着变化。

After the instance is in place, it is then possible to use the logs to pinpoint errors or use the post-processing scripts to identify performance or failure trends over multiple runs of the instance.

当实例位于恰当的位置并运行了多次之后，就可以使用日志查明错误或使用后处理程序脚本确定性能或故障趋势。

A particular unit might fail frequently, but the only consequence apparent at the application level is spooky variations in over-all performance.

特定的单元可能经常发生故障，但是在应用程序级别出现的唯一结果是在整体性能方面的各种怪异变化。

As of this writing, the current version is still a beta, and even after it's released commercial or open source projects may improve performance over the reference implementation.

在撰写本文的时候，当前版本仍然是测试版，只有当它作为商业或开放源码项目发布以后，它的性能才可能优于参考实现。
