    Hi,

    Thanks for providing a great theme(bought three licenses, two for friends because it’s so good). I have been able to compete with small business competitors paying a hundred dollars a month on SEOshop alone, both visually and performance wise.

    I am running your theme with Nginx and APC (through W3 Total cache) for performance.
    On my laptop, the website is snappy, except for the product images. They take a blink of an eye extra time to load. At first it made sense to me, because images take longer to load. However, even after server-side caching as well as browser caching, the image still takes the same time to load(browser caching should have nullified the time needed to load, right?).
    On my mobile, the image load time is much worse, after most elements have loaded, the image really takes time to load.

    W3TC Minify breaks the theme easily so can’t use that reliably and hosting the site over multiple subdomains (e.g. static1.domain.com, static2…) to increase simulteanous HTTP requests seems difficult. I have New Relic installed but haven’t been able to find where the exact bottleneck might be. New Relic support’s first advice was to check any slow AJAX calls, but didn’t see anything interesting with my rookie eyes.

    Do you have tips on where the source of the problem might be?

    Hi,

    If I run your site through this speed test, it looks like the server is a little lagging. (Yellow bars) : http://tools.pingdom.com/fpt/#!/ez6vFM/https://mrhinkle.nl/

    – Your favicon is also showing a 404 error, which will slow things down.
    – Have you tested combining only the CSS files with your cache plugin and not the JS files. Each asset is waiting for the server to respond before it loads.

    Thanks.

    Thanks for the fast reply!

    I could not find the favicon (error) in your waterfall or in mine, but reuploaded it in the Dante Theme Options,just to make sure.

    I tried combining CSS on Disk and with APC, both broke the site significantly. I guess manually, carefully combining would be the only way, which did not turn out very well the last time I tried that. Should I combine them in the order of the waterfall, to prevent any dependency errors?
    What could be reasons of server delay? I am running one core with 1gb RAM. But I have a lot of RAM left.

    This is out of the scope of the theme, initially I thought the problem was something JS theme related (the lightbox image gallery on each product page), so if you cannot provide a lot of support, I’ll understand 🙂

    Sorry for double post, couldn’t edit. I also see that the same CSS file is loaded multiple times with different version numbers ( style.css?ver=4.4.1, style.css?ver=2.0.3 etc.) Is this a flaw or normal?

    I think I will skip the minifying and wait until HTTP2 is mature with Nginx, so concurrent requests is no problem. I have Nginx reverse proxy enabled to cache directly (insanely fast) from Nginx as well as APC+W3 total cache. I highly doubt it is my system’s problem or a Dante theme problem, rather poor performance from flexslider. It is too much to ask for you to fix this, but glad that I have found the problem.

    Thanks.
