Bad result, slow pages - enurs - 09-16-2012 04:56 AM

Hi,

We have tried to optimize our webpage ibutikk.no
It pulls lots of data from provider and as you might see its a comparison site for products.
I am testing with this link: http://www.ibutikk.no/cat/digitale-kamera/124901
And result you can see here: http://www.webpagetest.org/result/120915_KQ_AG0/
We run a VPS server with 5gig ram and 4 cpu on fast UK lines
I would really appreciate any help you can give.
Thank you

You are going to have to use something like New Relic or add some instrumentation to your back-end to get the details on the long first byte times. Since you already mentioned that you are pulling data from a provider, do you know what the performance characteristics of the calls for that data is?

- Do you make one call to the provider to fetch all of the data or do you have to make several?
- How long does each call to the provider take?
- Do you have SLA's?
- Are you allowed to cache the responses?

Blocking back-end calls to an external data provider are performance killers even when done right.
