Hi there,

Thanks for your earlier detailed response, it was really helpful.
I wanted to follow up with two additional questions:

1. About Object Caching (Redis/APCu)

I’m currently using LiteSpeed Cache, not WP Rocket, and I understand that object caching (like Redis or Memcached) can significantly improve performance. especially for dynamic sites like mine (WooCommerce + Elementor + WoodMart).
Unfortunately, I’m on Namecheap’s Stellar Plus shared hosting, which doesn’t allow Redis/Memcached due to shared resource restrictions. While APCu is available in the PHP selector, it doesn’t seem fully active server-side, and Namecheap’s support confirmed it can’t be guaranteed on this plan. They’ve recommended moving to VPS or EasyWP for persistent object caching support.

My question is:
How much impact would proper object caching (Redis/APCu) have on real user experience?

2. High Initial Document Request Latency

I’ve noticed PageSpeed Insights reports high document request latency, particularly:

• Mobile: Estimated savings of 2,630 ms, server response observed ~2.7s
• Desktop: Estimated savings of 1,110 ms, server response ~1.2s

This seems to be affecting my LCP and overall load speed, even though I’ve enabled full-page caching with LiteSpeed.

Here’s what I’ve already done:

• Enabled LiteSpeed Cache (page cache, browser cache, guest mode)
• Minified and deferred JS/CSS
• Lazy-loaded images
• Removed unnecessary plugins

Despite this, the first document load (HTML) is still slow.

Would you recommend any WoodMart-specific techniques to reduce this initial response time?<br>
Or is the only real fix to upgrade hosting (e.g., EasyWP or VPS) to reduce backend processing time?

Thanks again!
