What’s the possible or the main reason to cause this
i am using litespeed cache for caching but most of the times there is always at least 4 sec initial delay
the server response time for some pages ar even at 7 sec
nothing worked even though i have a good score on pagespeed and gtmetrix

https://i.sstatic.net/1KCCOwV3.png

I’m using W3 Total Cache plugin, and I have an critical issue warning from WordPress site health tool:

Page cache is detected but the server response time is still slow
Median server response time was 2.587 milliseconds. It should be less than the recommended 600 milliseconds threshold.

I really appreciate any help you can provide.

Best regards,
Milos

I was using WP Rocket until a few days ago and switched over to Litespeed 3 days ago.

On GTMetrix, my site shows LCP of 4.1s and Performance as 55%, Grade D

whereas with WP Rocket , I always achieved Grade A, Performance 95-100% and LCP of about 150ms.

I want to stay with Litespeed and need your help to make my site score as close to what i was achieving earlier.

I just read one of your replies to someone from 2 years ago & did the setting for crawler too.

Let me know if you can help me resolve

Thanks

Hi, I am having a caching issues that I believe are related to the Redis object cache. It shows up consistently after awhile on normal site pages but more drastically on woo commerce related pages. I have a website with around 2000 products and 80,000ish variations. So my sitemap is quiet big (which I supplied to the plugin also) I’ve noticed having this many variations while using woo commerce results in a large database ( my post meta table is over a million rows that I cant really clean because the bulk of it is from Woo commerce when it created my product variations. This large db while ugly does not seem to be effecting load like crazy according to Query Monitor Plugin. )

I believe my issue could be a mix of Redis and PHP settings on the server not allowing enough resources to be allocated and my configuration of the plugins settings (Browser/Page/Object tabs).

I have attempted some troubleshooting and tweaks and I believe that I have the object cache running because

1. if I’m logged out and I visit a page twice (not just refresh but leave and come back) it’ll load instantly the second time around.
2. It also works If I access a product page on PC1 and then access it again on a different PC right away, it will load fine most of the time. (sometimes PC2 will still experience long load time. usually always the document and waiting for server response time.)

This ‘test’ I do also only works for a few minutes because after ~5 minutes, maybe less I will experience slow load times on all of my pages and the network inspect during this load shows the document file primarily taking up the bulk of that time Waiting for server response.

It feels like my objects are being uncached even though the message by W3 at the bottom of the page shows around the same range of objects being cached on this page during slow and fast times. (this is typically on the Woocommerce pages but also home)

The Home page can also experience the long load times on the first visit if it hasn’t been visited recently. (but longer than the shop or product page) I’ve noticied that The W3 banner at the bottom will show a wide range of numbers here sometimes showing 48 / 792 object caching or 582 / 1493 but load some what quickly both times, does this number not really matter or do I not understand it?

It might be my lack of cache knowledge but is this supposed to ever fill up or stay at a consistent number? seems to move around. I know this space will give a warning too for blocked like when you’re logged in but I see no rejected when logged out so its not that at least.

Brief Settings (maybe there’s a better way to export these):

• Page Cache – Enabled – Redis
• Minify – Disabled
• Opcode Cache – Enabled – Opcode: Zend Opcache
• Database Cache Disabled
• Object Cache – Enabled – Redis
• Browser Cache – Enabled

Page Cache Settings

• General block is almost all enabled, “Cache URI’s with query string variables” isn’t enabled. also don’t cache pages for logged in users is enabled as well.
• Cache Preload = Automatically Prime the page cache,
• Updated interval = 900 seconds & Pages Per = 20 ( I do not understand what this is doing exactly and what combo of numbers helps here should I lower the interval and increase the pages per? )
• sitemap url is given and preload upon publish is checked.
• Late Initialization is unchecked ( would enabling this help )
• Persistent Connection is checked also.
• Connection Timeout + retry interval + timeout is all 0.
• Max Lifetime of cache objects = 3600 seconds (is this the expiry that I experience? does this mean it cleans everything and no pages load fast without a prior visit again? or does the Updated interval cycle through my pages and do this? but it wouldn’t complete in time if the expiry is that low. correct?)
• Never cache the following pages: wp-.*\.php & index\.php
• Rejected cookies ( woocommerce_items_in_cart, woocommerce_cart_hash, wp_woocommerce_session_, wordpress_logged_in )

Object Cache Settings

• Enabled Persistent connection
• Connection timeout, interval, read timeout are all 0
• Default lifetime of cache objects 180 seconds (again same question as above, and by larger the cache they mean more ram usage?)
• Garbage collection interval = 3600 seconds (This was greyed out in the page cache but not object cache, is this setting important?)
• Non-persistant groups: = counts, plugins
• Store transients in database is also checked.

Browser Cache settings

• This has a lot of combos and not sure what is custom and default. but I do see expires header and lifetime of 3600 here too.

If I had to take some guesses

• makes me feel it is an expires things?
• physical memory + redis arent configured (?)
• not grab everything (ignore woo)
• Conflict ( I use Avada Theme, & Jetpack but I’ve made sure to turn off conflicting settings like gzip. I have search console access and had to install redis myself and maybe configured it incorrectly as I was originally using the ‘Redis Object Cache’ plugin by Till Kruss )

REDIS STATS INFO

I have checked $redis-cli info stats and these are the values its provided

Total_connections_received: 821

Total_commands_processed 361million

total_net_input_bytes 890billion

total_net_output_bytes 3Trillion

expired_keys: 61million

expired_state_perc 16.31% | | Evicted Keys: 407k |

expired_time_cap_reached_count 1,027

keyspace_hits: 124million || keyspace_misses: 126million

I’ve called $redis-cli monitor and it always shows a lot, and fast. no time to really read but i can see entries that include W3TC in it.

Any and all help is useful (: I’m willing to read documentation and provide more info / status reports. or if this is too personal for these forums maybe a more direct channel to contact W3?

Thanks

Reduce initial server response time

When I disable the plugin, the page speed score goes up. I have tested this on multiple websites. I think it has to do with the QUIC.cloud CDN.

Report Numbers

Can you please check if you also think it is too slow? Ideally, it should open within 1-2 seconds.

Is it an option to create the site from scratch? (do a fresh install)

Thanks.

My website only scores on 12 for the mobile site on google pagespeed insights, while desktop site is relatively decent 52 (not that great too)

The first recommendation given by google is to “Reduce initial server response time
5.35 s”. Been toggling with different settings but nothing improved. Please help. Thanks in advance!

How to fix this?
