VPS Suggestion recommendation for WooCommerce website

Cloudflare usually helps with exception of 2 geographical locations, India and Australia. India CF servers is only available with consistency on Cloudflare Business plan or higher and Australia CF servers has varying degrees of consistency starting at sometimes on Pro plan to most of the time on Cloudflare Business or higher plans. This is due to the peering arrangements and costs for Indian and Australian ISPs with Cloudflare = basically it costs alot of money for Indian and Australian bandwidth so Cloudflare can not provide it on CF Free plan and only sometimes on Pro. What happens is CF Free plan users will have Indian traffic routed to Singapore datacenter. Australian visitors can have traffic routed to Singapore, Japan or more likely Los Angeles.

If you are a for profit site and make enough money, then Cloudflare Business plan is worth it at US$200/month to guarantee India visitors most likely hit Indian CF datacenters (sometimes Singapore gets routed). Only Cloudflare Enterprise plan will have more likely routing to CF Indian datacenters.

Cloudflare does not cache HTML content by default only static assets i.e. css/js/images (see below). So for optimal TTFB speed, you want your origin real web server to be hosted in a location closest to your majority traffic visitors and then put Cloudflare in front. For instance, my forums has 50% US visitors 40% Asian visitors and 10% Oceania. So my optimal geographic location for my origin is US West Coast as it sits in middle of US, Europe and Asian so equal round trip times for majority of visitors.

Cloudflare cache certain static content Understanding Cloudflare's CDN but not dynamic/static generated html itself by default (which is what WPT TTFB is testing for). But you can tell Cloudflare to cache dynamic/static generated html content to some extent depending on Cloudflare plan you’re on via cache everything page rule but have to be careful to only do this for static html content and not dynamic html content (otherwise you would cache private logged in user content).

• How do I cache static HTML?
• How Do I Tell Cloudflare What to Cache?
• https://blog.Cloudflare.com/caching-anonymous-page-views/ on CF Business plan you can properly distinguish between logged in users versus guests so tell Cloudflare via bypass cache on cookie page rules to only cache for guests the dynamic/static generated html content and bypass cache for logged in users. Then on CF Business plan you have access to Railgun which allows you to accelerate dynamic generated html content for the logged in users Railgun™ | Cloudflare. Then there’s also Argo for optimising the routing to your origin as well Argo Smart Routing | Dynamic Content | Cloudflare

FYI, all your screenshots have broken images so I can't see the images.

If majority of visitors are in India, then Linode India + DDOS would be best. Just spin up a few Linode's and inspect their cpu model to make sure you land and choose a newer faster cpu like AMD EPYC 7401, 7451 or 7501 instead of older Intel Xeon E5-2680v2/v3 Linode - Guessing Linode's next server cpus ?

Use command below to see what cpu model is used

Also GTMetrix isn't very useful overall especially if you want to test geographical regions not available. Use webpagetest.org to test different geographical regions and different browsers and mobile devices WebPerf - PageSpeed - How to use webpagetest.org for page load speed testing

 

Yeah also get them to unblock your SMTP email port on Linode account so you can send outbound emails via Postfix.

 

That's the best way. Hope you can get it cleared up.
