Slow TTFB on First Load, Subsequent Page Loads Quicker

[Guest]

When I run on webpagetest.org I get 10-14s TTFB on first load, and 1.4s on subsequent refreshes. 

 

I get the same results on my own browsers.

 

Debug profiling doesn't really help because it is a TTFB issue and most of the time the profiling looks fine.

 

I've tried disabling all modules.

 

I use PS 1.6.0.9 and enabled the hotfix available that I found re: slow FO/BO.

 

Any ideas?

What's wrong? The first load is always longer. PrestaShop can compile all templates as well as you can have a large number of calls (images, styles) on the page. Can you share the URL?

Thanks for the response tuk, really appreciate it!

 

The url is shopiwillbringchange.com

 

I can understand being longer on the first load, but 10-14s seems a little long? We only have 1 product and category.

 

It sometimes happens even on subsequent loads that are not the first load but it is sporadic and not easily reproducible and not so long but around 4-5s.

 

We are on shared host, could that be the primary reason?

I loaded the home page. It took around 5 s (6am).

 

shopiwillbringchange.com - TTFB 0.4 s

en/ - TTFB 2.5 s (6 kB)

...css - TTFB 0.2 s

 

It looks like your server is "slow" on PHP or MySQL. It must be even worse within rush hours.

Edit: Compare these times with my site at a shared hosting

 

www.presta-addons.com - TTFB 0.2 s

en/ - TTFB 0.7 s (20 kB)

...css - TTFB 0.04 s

Hi tuk,

 

Thanks for taking a look at that for me.

 

It's odd, we are using Site5 which I thought was a fairly reputable company at least for shared hosting.

 

Is this something I should be complaining about? What can I even ask?

 

I've been talking to their support but they basically just keep giving me the runaround.

I would leave them. Hostings are like shifting sands. One day everything is all right and after several weeks your server is overloaded.

Thanks for the advice tuk, appreciate it.
