什么是GWT字节缓存文件？ [英] What is the GWT byte-cache file?

问题描述

作为一个背景，今天，我的GWT托管模式运行的速度很慢，达到了几乎不起作用的程度。每当我暂停应用程序时，相关的线程（主线程，代码服务器等）都在等待一些文件I / O本地方法。我挠了一下脑后，试图清理硬盘。然后，我刚才在用户的 Temp 文件夹中发现了一个名为 gwt7155307955598297091byte-cache 的4千兆字节文件。我想知道这个文件可能会有什么用处，如果我完全删除它会发生什么。我下次启动开发模式等待字节缓存被重新创建时会出现性能问题吗？

>查看 gwt源代码，它表示它是全局共享磁盘缓存，由链接器（com.google.gwt.core.ext.linker包）和编译器（com .google.gwt.dev.javac包）。

As a background, today, my GWT hosted mode runs just mysteriously slowed down to the extent that it is virtually not working. Whenever I pause the application the relevant threads (the main thread, the code server, etc.) are waiting on some file I/O native method. After scratching my head for a while I tried to clean up my hard disk a bit. Then I just discovered in my user's Temp folder a 4 gigabyte file named gwt7155307955598297091byte-cache. I wonder what this file may be good for, and what will happen if I delete it completely. Will I have a performance issue the next time I start the dev mode waiting for the "byte-cache" to be recreated?

解决方案

Looking at the gwt source code, it says it's "A global shared Disk cache", used by a linker (com.google.gwt.core.ext.linker package) and compiler (com.google.gwt.dev.javac package).
