Question
We picked the wrong company to put us on a WooCommerce platform and they almost put us out of business. The site is stable now, but the speed is inconsistent. We have a good hosting company and need someone that can look at the code and find what is causing the site to slow down. Everyone we have talked to is unable to find the cause.
Answer
Is the speed "inconsistent" as in sometimes a specific page is fast and sometimes it's slow? Or are the same elements always slow? Perhaps you've already done this, but run the front-end through some tests on Pingdom first: http://tools.pingdom.com/fpt/ That's where I'd start if it was one of my client sites. From there I'd run the P3 plugin to see if there was a specific plugin causing any issues (https://wordpress.org/plugins/p3-profiler/). I have a few other things I check for but these first two are easy enough for a non-tech to at least get started.
