什么是GWT字节缓存文件？

Question

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?

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）使用。 。
