What does "wo site create site.tld --wprocket" actually do?

alex

Hello,

I know there is a command for Wp-rocket:
wo site create site.tld --wprocket
and it will specifically setup Nginx for Wp-rocket, right?

If yes, I am quite confused because it is not required to setup Nginx for Wp-rocket according to Wp Rocket official installation document at https://docs.wp-rocket.me/article/6-installing-wp-rocket

So, anyone would like to share the points for the site created by "wo site create site.tld --wprocket"?

Is there a Redis object cache or Nginx FastCGI Cache running on the server end with Wp-rocket actually in this case?
If not, Why specially configure Nginx for Wp Rocket?
If yes, which cache is running? Redis Object cache or Nginx FastCGI Cache?

Thanks so much

marty

If you look at wo site edit yoursite.com you'll see that WO works by includeing various config files from /etc/nginx/common/. One of which will be wprocket-phpXX.conf for a site created with --wprocket.
So if you look in e.g. wprocket-php81.conf you can see exactly what is being done.
i.e. Nginx tries to load the cached files directly from where WPRocket creates them. Without that config it will still work but will need to load WordPress/PHP so WPRocket can output the cached files. So it should therefore be faster.
Or you could just use Nginx FastCGI Cache and not bother with WPRocket. ;-)

marty , Thanks so much.

So, it means Wo create a set of optimized configuration specifically for WP Rocket?

In this situation, it means that the server runs ONLY with the Wp-rocket page cache, but there is no other cache like Nginx FastCGI Cache or Redis Object Cache??

Thanks

marty

alexlii1971 Yes, using the --wprocket flag creates a config specifically for use with WPRocket... (!)
No, it doesn't add any other page cache on the server (because you wouldn't want more than one).
It also doesn't add Redis as an object cache. But you can do that manually if you want to.

Hi Marty,

Is there any tutorial here to show how to setup both Wp-Rocket and Redis object cache working together.

alex

marty It also doesn't add Redis as an object cache. But you can do that manually if you want to.

By the way, I noted that WP-rocket is really eat both CPU and Memory resource. It is not what I expected.
Nginx Fastci cache works on server end, I did not found a way to make Nginx Fastci cache and Redis Object Cache working together, is it possible?

Thanks

Not that I know of.
But essentially it's just install Redis sudo wo stack install --redis.
Then add the 'Redis Object Cache' WP plugin, and turn it on. :-)
As far as I know WPRocket doesn't do anything around object caching so there is no setup for it.

I'm not a fan of it. I think the 20% commissions have a lot to do with how often it gets 'recommended'. ¯_(ツ)_/¯

Nginx Fastci cache works on server end, I did not found a way to make Nginx Fastci cache and Redis Object Cache working together, is it possible?

Yes. Just install/update the site with --wpfc, then do above to add Redis as an object cache.

marty Yes. Just install/update the site with --wpfc, then do above to add Redis as an object cache.

ok, I already setup them by command: wo site update mysite.com --wpsubdir --wpfc, before updating site, it is in redis cache mode:

1# I am using Object Cache Pro before updating site to be Nginx Fastci cache
2# After updating, I just note that it is still in the mode of Redis cache on Nginx Helper, so I manually change it to be nginx Fastcgi cache.

Here is a screenshot of nginx helper after update:
https://prnt.sc/WEREoCt_hZRO

in Wp-config, I set following line for Redis pro:

/* Redis Pro Plugin */
define( 'WP_REDIS_CONFIG', [
'token' => 'from object pro',
'host' => '127.0.0.1',
'port' => 6379,
'database' => 0, // change for each site
'maxttl' => 3600 * 24 * 7, // 7 days
'timeout' => 1.0,
'read_timeout' => 1.0,
'retries' => 5,
'retry_interval' => 300,
'split_alloptions' => true,
'compression' => 'zstd',
'serializer' => 'igbinary',
'async_flush' => true,
'split_alloptions' => true,
'prefetch' => true,
'debug' => false,
'save_commands' => false,
]);

define('WP_REDIS_DISABLED', getenv('WP_REDIS_DISABLED') ?: false);

Anything else did I need to do please?

By the way, Wp-Rockect eat so much CPU, Memory, and Disk I/O, so I do not want to use it for cache.
But, Wp-rocket support to achieve high score on pingdom, lighthouse, and gtmetrix.

So, is there any other way to achieve high score without using Wp-rocket, or any other peformace plugins?

marty

alex Anything else did I need to do please?

I don't use the pro version so not 100% sure. But the plugin will confirm that it's working & provide stats, and you can check page headers to confirm the page cache is working.

alex So, is there any other way to achieve high score without using Wp-rocket, or any other peformace plugins?

It depends why the scores aren't high. You have to dig in to the details of the reports. But perfect scores are just a vanity metric anyway. :-)

Ok, here is screenshot of cache setting now:

Site was updated with --Nginx fastcgi cache, but also Redis cache Pro is activated, and nginx Fastcgi cache is checked in Nginx Helper:

Yes, that is what I thought before, but I recently recieved the email from Google, and I realize that google take Web Core Vital into a key for ranking.

For now, ** the site is quite slow both frontend and backend. It would be great If there is any suggestion on optimization to improve the speed.**
