https://www.phoronix.com/news/Intel-Linux-3888.9-Performance 难道说之前升级内核以后 EPYC 7001 跑benchmark性能低了16%是这么来的？先前的Bug Report：https://bugzilla.suse.com/show_bug.cgi?id=1229012 升级内核前后的benchmark对比：https://github.com/jiegec/blog-source/commit/b41b6d5317f5fe00908…

这个问题在ARM64的设备上也有类似的表现：https://github.com/jiegec/blog-source/commit/e88455df6b343d0d58ac05e98da1a85f110c2e41
等升级6.12内核再重测吧。。此外新内核的deepsjeng_r反而变慢了，虽然慢的不多，对最终的分数影响比较小。
