Linux 3.9 To Linux 4.9 Kernel Benchmarks: Testing The 21 Last Kernels
Written by Michael Larabel in Software on 25 October 2016. Page 8 of 8. 11 Comments

Somewhat similar to PostgreSQL, the Redis benchmark results fluctuated a lot too over the course of the kernels of these past few years.

But the Redis results with Linux 4.9 are roughly in line with the fastest results on the older kernel releases.

Similar to what we've seen with some of the other tests, since Linux 4.6 the performance did drop off for the Apache web-server test, but hasn't recovered as of Linux 4.9 Git last week.

Well, that's what the Linux kernel performance looks like over the course of the past 21 versions going back to Linux 3.9. For the most part the results are very good with Linux 4.9 overall being faster than Linux 3.9 on the same Core i7 4790K system, especially when it comes to the disk/EXT4 performance and graphics. The more compute-focused results were more of a toss-up with some wins but there are also some regressions, on a few of the tests indicating slowdowns post-4.6.
