Ok, i have come to the end of my tether on fixing the speed of my site. I have spent hours and days researching and applying all methods to get the page load speed to improve, whilst i've noticed some improvements with 90% of my extensions currently disabled it's still not how it should be.
I have a relatively high spec server - 32GB RAM, 512GB SSD drives, intel 8core cpu, apache + varnish + cloudlinux with many tweakings done to mysql, php etc
I will outline what i've done so far:
- GZIP Compression - ON
- Varnish on backend - ON
- Nexcess Turpentine - ON
- Compress CSS + JS
- Deactivated near enough all extensions apart from whats needed
- Use of CDN (cloudflare)
- Optimization of images
Yet i still get a page load time of around 4.5 seconds on average.
The only thing i can think of it being is the theme? I've hit a brick wall on my limited level of expertise and always try and find out how to do fix things before posting, i've become desperate for some assistance.

Profiler Results (click screenshots to enlarge)
Following onto the comments regarding AOE Profile, these are the results:
I've sorted it from the highest time, i see a lot of time is being taken up by catalog_category_view. Where do i start with this?
Nearly all of my navigation has a catalogue url rewrite, would that cause this? Profiler shows left-products.phtml as the culprit?
