升级GCS Connector hadoop3-2.2.8后文件操作性能骤降求助

我的Java应用实现了基于Hadoop文件系统的文件层封装类File，近期将GCS Connector从hadoop3-1.9.17升级至hadoop3-2.2.8（使用shaded jar）。该File类核心读写方法实现如下：

class File {
    private String path;
    private FileSystem fs;
}

@Override
public OutputStream write(boolean overwriteIfExists) throws IOException {
    return fs.create(path, overwriteIfExists);
}

@Override
public InputStream read() throws IOException {
    return fs.open(path);
}

通过多线程性能测试（每个线程创建对应特定路径的File实例并执行READ、RENAME、EXISTS、CREATE等操作）发现，新版本Connector的各项操作平均耗时远高于旧版本：

operation, hadoop3-1.9.17, hadoop3-2.2.8
READ       4542.71,        10171.26, (旧版本的2倍)
RENAME     1347.75,        4483.27,  (旧版本的4倍)
EXISTS     47.23,          1538.74,  (旧版本的50倍)
CREATE     570.1,          1539.81,  (旧版本的3倍)

已参考GitHub Issue #114调整配置但无性能改善，现咨询两个问题：

1. 有无优化上述操作性能的参数配置指南？
2. 即使使用shaded jar，类路径中的其他依赖jar是否可能引发兼容性问题？当前类路径包含以下jar：
