Wordpress Wordpress 123.09beta01 Load Testing on Vultr Sydney KVM VPS

Setup a 2GB, 1 CPU Sydney Vultr KVM VPS server to test Centmin Mod 123.09beta01 with betainstaller7.sh installer to default to PHP 7.0.18+ for Loader.io testing as one Centmin Mod user was having issues with Loader.io testing of a Vultr 2GB Sydney KVM VPS which seems to be related to differences in out of box tuning for Centmin Mod 123.08stable vs more improved 123.09beta01.

-------------------------------------------------------------
Setup full Nginx vhost + Wordpress + WP Plugins
-------------------------------------------------------------

---------------------------------------------------------------
Important Information
---------------------------------------------------------------

You are about to create an Wordpress based Nginx vhost site with
or without HTTPS/SSL support.
Also read the continually updated Getting Started Guide
at centminmod.com/getstarted.html if you haven't already
---------------------------------------------------------------
403 Permission denied message handling
if after vhost site setup you encounter 403 permission denied errors,
check https://community.centminmod.com/threads/11215/ to see if your
site needs tools/autoprotect.sh tweaking & whitelisting
---------------------------------------------------------------

Do you want to continue with Nginx vhost site creation ? [y/n] y

Enter vhost domain name you want to add (without www. prefix): test.domain.com

Code (Text):

Default is to install KeyCDN WP Cache Enabler Plugin
as it's more stable and reliable than WP Super Cache.
Redis cache may have issues with caching due to long 6hr cache TTL
You can select which caching method to use below:

--------------------------------------------------------
        Wordpress Caching            
--------------------------------------------------------
1). KeyCDN Cache Enabler (default & recommended)
2). Redis Nginx Level Caching (may have issues with some wp plugins)
3). Wordpress Super Cache
--------------------------------------------------------
Enter option [ 1 - 3 ] 1

General Notes

Loader.io and any benchmark testing is subject to relative distance between test server and target server (Centmin Mod). Geographically longer distances means ping times and thus round trip response times for tests are much larger which affect the benchmark test results. So New York, USA test server testing New York based Centmin Mod server may have less than 10 milliseconds ping and response times. While New York test server with Sydney, Australia based Centmin Mod server may have 250-280 milliseconds response times.

KeyCDN Cacher Enabler

KeyCDN Cacher Enabler is the selected default Wordpress caching setup which is an improved version of WP Super Cache for full page static WP caching. Need to enable some settings in Cache Enabler Settings area.

Ideally set a Cache Expiry time in hours instead of 0

Loader.io Test Paramenters

Testing using Loader.io free plan for 'Maintained Client Load' testing between 200 to 1000 users for 1 minute.

Testing 2 configurations:

1. 1st config - where default is no gzip compressed http request headers so server serves non-compressed files.
2. 2nd config - is with Accept-Encoding: gzip, deflate, sdch, br http request headers so server serves gzip or brotli compressed static files (usual default web browser behaviour).

 

Loader.io No compress

 

Loader.io Compress

Loader.io uses AWS infrastructure, so let's see where these test IPs come from geographically speaking

From Amazon AWS Ashburn datacenter which is US East coast so one of the furthest away locations for testing a Sydney, Austrlia VPS so hence the 200-300 ms response times from Loader.io testing.

 

Enable Performance Options

Centmin Mod 123.09beta01 has additional performance options you can enable for both Nginx and PHP-FPM.

You set them in persistent config file you create or append to at /etc/centminmod/custom_config.inc

Code (Text):

CLANG='n'
PHP_PGO='y'
GCCINTEL_PHP='y'
DEVTOOLSETSIX='n'
NGINX_DEVTOOLSETGCC='y'
NGXDYNAMIC_BROTLI='y'
NGINX_LIBBROTLI='y'

• CLANG='n' - disable clang compiler for Nginx and use GCC
  
• PHP_PGO='y' - enable PHP 7 Profile Guide Optimisations for +3-17% extra boost over PHP 7 standard installs
• GCCINTEL_PHP='y' - enable Intel cpu optimised compilation for PHP-FPM
• DEVTOOLSETSIX='n' - don't use devtoolset-6 GCC 6.21 only use devtoolset-4 GCC 5.31 when paired with next setting
• NGINX_DEVTOOLSETGCC='y' - enable devtoolset-4 GCC 5.3.1 Intel cpu optimised Nginx compilation
• NGXDYNAMIC_BROTLI='y' - enable brotli dynamic nginx module support
• NGINX_LIBBROTLI='y' - enable brotli nginx module support

Then recompile nginx and php-fpm via centmin.sh menu options 4 and 5 specifying the nginx and php-fpm versions you want to compile i.e. 1.11.13 and 7.0.18 respectively.

You can compile Zend OPcache (Zend Optimizer Plus+) support
as an alternative to using APC Cache or Xcache cache.
But Zend OPcache only provides PHP opcode cache and
DOESN'T do data caching, so if you web apps such as Wordpress,
Drupal or vBulletin require data caching to APC or Xcache,
it won't work with Zend OPcache.

Do you want to use Zend OPcache [y/n] ? y
