树复制 meaning in Chinese

tree copying

My performance and tuning tests were primarily focused around extracting an uncompressed kernel source tarball from a ram disk to the test filesystem , and then recursively copying the new source tree to a new directory on the same filesystem
我的性能和调整测试主要是关于将ram磁盘中未压缩的内核源文件tar包（ tarball ）抽取到要测试的文件系统，然后递归地将新源文件树复制到同一文件系统中的一个新目录中。
