Wordpress WPPerformanceTester Results

This slowdown happens only with Hetzner's servers, HDD/NVMe both alike. With similar specs on NexusBytes the PHPBench is a tiny bit slower, but the more important req/s is 25% faster and more stable. So I assume this has something to do with CPU throttling, or something like that.

---

EDIT: OK, changing the governor frequency-set fixed this, I get now a pretty stable reading:
3.2 / 2900
EDIT2: With GCC9/PHP7.4: 3.2 / 3200

 

Avoro AMD EPYC special (1 dedicated CPU core, 5 GB DDR4 ECC RAM)
Price: EUR 12.60 / quarterly (including VAT)

5.0 / 1300

 

Eurohoster High performance VPS 2xvCPU (Intel® Xeon® E-2278G)
4.9 / 2600
*only 100MB connection.. (can be upgraded to max 300MB/s)

 

Indeed. The latest performance benchmarks I've seen do not agree with this, but I have a feeling (no valid proof yet) that at least on WP environment Intel's latest can serve more requests per second per core. Most likely not winning when the cost is calculated in, though. Let's see when someone makes a more throughout testing (wink wink).

 

Upcloud 2CPU (Epyc)

4.1 / 2100-2300
EDIT: 4.0 / 2400-2600 when nginx / php is rebuilt with pgo/GCC9.

 

Nice performance compared to $500+ / month

I wonder if PHP Bench result can get better with PHP socket (~200ms improvement?)

 

Currently testing Hetzner AX101 which is Ryzen 5950x based (Zen3), and as such not compatible with Centminmod yet (CentOS Project Shifts Focus To CentOS 8 Stream Effectively Ending CentOS 8 In 2021).

With Ubuntu 20.04 / Kernel 5.11rc7 / Nginx 1.18&PHP 7.4.15 / Governance set to performance I already get
1.998 / 3500 for WP performance Tester benchmark result. Will update here when I get result for Centminmod based install.

 

With Hetzner EX100 (Intel® Core™ i9-12900K) and Centminmod 130.00beta PHP 8.1


Note: From WP Performance Tester changelog
2.0.0

Code:

(December 29, 2021) Major update and version change.

Plugin should now be compatible with latest PHP 8 / MySQL 8.

Benchmarks no longer comparable between versions. Industry benchmarks will only show results from the same version.

benchmark script updated to replace deprecated/broken math functions and mysql functions. Version number in benchmark script reflects version number of current open source library it was based on, NOT WPPerformanceTester version number.

ENCODE() replaced with AES_ENCRYPT to perform mysql benchmark.

 

Formally that's the case. In practice you can shave off around 1 sec from PHP Bench (upper section), so that would be 2,6 sec for Core™ i9-12900K and you have comparable benchmark
