Dude. You are as they say 'The Man'.

1 sec is too slow for a page to generate. This has made things so much better. I salute you!

however, that is for manufacturer list displays. A category with 47 products and 1 subcategory still takes 2.5 secs.

I was going to try to retrofit it from 4.1 but its too nasty so I have a simplified version in the works. Iits horrible the price we pay for multilingual capabilities on a single language site. The second will speed up the product page if you use variants. The more variants the more improvement. Seems X-Cart asks for the tax rate for each variant - but the tax rate is only dependent on the product. So it goes through a ton of work for every variant when it only needs to do it once. They tried to cache some of that work but they screwed it up and it only works for logged in users. And they didn't cache the results at a higher level routine so it doesn't have that much affect. This one will apply to both 4.0 and 4.1. Stay tuned. I'll post these later this week or next week.

geckoday,

I can't wait for your other performance boosters! Thanks for this tip. I had just upgraded a few shopping carts and and the same time changed hosting providers, and I couldn't figure out why the sites were running so slow.

This little tidbit improved performance quite a bit.

Thanks again.

Wow. It sure does improve performance. Thanks.

Wow, that's neat... How do you get that those timing comments to appear in the code?

So it looks like the slow func is func_bf_psc (see blowfish.php). It is also used in func_tpl_postfilter(). Not sure what it is actually doing. Seems to be the decrypt of $r?

Wow, very cool, thank you!

My main page is huge, tons of HEAVY-weight mods, and I get this:


Don't know what it was pre-mod. I did this mod awhile ago. (thanks!)

I was having trouble getting the benchmark times to display. With Jasmin's help, I now see my site's benchmarks. Here's how...

In your browser's address bar type in:
http://www.yourdomain.com/home.php?benchmark=y

Replace yourdomain.com with the domain name of your X-cart store. Make sure you use the full path to the page you want to test. I tried the original, http://www.yourdomain.com?benchmark=y and that didn't work for me, because the index.php page redirects to the home.php page.

Once you type in your Domain and Full Page Path plus the Question Mark and the Benchmark equals Yes, then hit your Enter/Return key and let the page load. Everything looks normal at this point. Now, you need to go to your browser's menu bar and select View Page Source Code. Scroll down to the bottom of the source code and you will see the page load times listed in an HTML comment.

Hope that helps anyone else trying to view their page load times. Jasmin, thanks again for your how-to tips.

Robert
