NVMe VPS RAM/CPU question

Anatoliy

Well-known member
Greetings! My forum is on NVMe VPS with 2 RAM and 2 CPU. Semrash says that Core Web Vitals are not good, and in GSC I see 2,5k pages under Core Web Vitals, while 8k under Pages (indexed). Can it be related that my server doesn't have enough of RAM/CPU? And if so is there a way I can see somewhere on the server is it luck of RAM, CPU, or both?

Thanks in advance.
 
That has nothing to do with each other.
Thanks for the answer. I like it because it means I don't need to do anything and to pay more for beefier server. )
However I thought that those first bite time and others are related to how fast a server sends to a client rendered page. Am I wrong ?

You’re partially right, things like Time to First Byte (TTFB) are influenced by how fast the server responds, but it’s not just about server power. It also depends on how optimized your site is behind the scenes.



One of the easiest ways to lower TTFB and speed things up is by implementing caching systems: page caching, object caching, or even server-level caching (like with LiteSpeed, or NGINX). Are you currently using any kind of caching setup?

I use redis. I set it up 3-4 years ago and didn't touch since then. I don't know if it works. I can see this in ACP but I don't understand what it means. Also I use cloudflare and serve cashed css & js. but again I set it up 3-4 years ago and didn't touch since then. Does redis info look ok?

If you can upgrade Redis to 7.2, you can upgrade it. You can also upgrade PHPRedis. You can also use allkeys-lru instead of noeviction as memory policy. I can only make suggestions about what can be done for free, but if you want me to do maintenance on your server, we can agree on a reasonable amount, you can reach me via DM for such a situation. Cloudflare configuration is also included in the maintenance.
 
I already asked tech support to upgrade redis and phpredis. Do hope it will help.
When the upgrade is completed, repost the two images again from your Admin panel with the new information. Also post your /src/config.php Redis configuration.
What XF version and what Redis Cache by @Xon addon version are you running?
 
XF2.3.6, Redis is now 7.2.5. Redis Cache by Xon 2.18.0.

Code:
$config['cache']['enabled'] = true;
$config['cache']['provider'] = 'SV\RedisCache\Redis';
$config['cache']['config'] = array(
        'server' => '127.0.0.1',
        'port' => 6379,
        'connect_retries' => 2,
        'use_lua' => true,
        'compress_data' => 2,
        'read_timeout' => 1,
        'timeout' => 1,
    );
$config['pageCache']['enabled'] = true;
$config['cache']['context']['page']['provider'] = 'Redis';
$config['cache']['context']['page']['config'] = ['host' => '127.0.0.1'];
$config['pageCache']['lifetime'] = 900;

if you want go up, don't use cache. google likes static web even it's slow, but not zig zag that bounces everytime.
1. remove robots text completely! google does not follow it anyway! transparency is important here!
2. make pages:
head > meta <meta name="robots" content="noindex,nofollow" />
index, follow > everywhere!

do not listen to everyone!

& see magic!
