hadoop - Hadoop 3.2.1 ErasureCoding ISA-L问题？

Question

我正在测试hadoop 3.0 Erasure编码。
为了进行测试，我在hadoop 3.2.1中上传了100GB，结果显示如下。 (5个数据节点)
3 COPY:150分钟
E C:250分钟(RS-3-2-1024k)
为了通过应用ISA-L来提高EC的速度，我对其进行了设置并测试了操作，但是速度却是相同的。
zlib:true /lib64/libz.so.1
zstd:假
活泼的:错误的
lz4:真实修订:10301
bzip2:错误
openssl:错误的构建不支持openssl。
ISA-L:true /lib64/libisal.so.2
(1)它是旧设备，所以我想知道CPU是否不支持它。
在哪里可以查看支持ISA-L的CPU的列表？

CPU : Intel(R) Xeon(R) CPU E5-2609 v2 @ 2.50GHz

(2)请告知是否有应用ISA-L的方法。

只提

Depending on the platform capability, Intel ISA-L can run on various Intel® processor families. Improvements are obtained by speeding up the computations through the use of the following instruction sets:

• Intel® AES-NI – Intel® Advanced Encryption Standard - New Instruction
• Intel® SSE – Intel® Streaming SIMD Extensions
• Intel® AVX – Intel® Advanced Vector Extensions
• Intel® AVX2 - Intel® Advanced Vector Extensions 2

Intel® ISA-L also includes unit tests, performance tests and samples written in C which can be used as usage examples.*
