We have an e-commerce site developed using magento 1.9.0.1, we could not able to reduce server response time to below one sec, (as per google page speed testing tool we have now 1.4 sec) we have tried almost all optimization process as below

1 - Using magento full page cache from well reputed company

2 - Added gzip compression

3 - Using cloudflare as CDN

4 - tried magento flat catalog table and disable unwanted indexes and make it indexing manually.

We have similar site running in USA with different name and its server response time is good, but it has less traffic.

Can anyone help/suggest some solution to reduce server response time?

Thanks Prajosh

  • something is fundamentally wrong with your site / server. Turn off your theme and go back to the default.. does that help? If not start to turn off your extensions 1 by 1 till you fine the culprit. If you have low traffic that processor is not the best choice and it would be worth swapping to a higher clocked e3 rather than a low clocked e5. However, that is a minor thing. A normal magneto site should be showing around 0.2 - 0.3 server response time. Also.. check your network card with ethtool.. is it showing the correct values or any errors? – Andy May 29 '17 at 12:48

If you have not already done so, you should install monitoring, gather data, and apply Scientific Method..

You need to spend time looking at your system, understand how it is performing and relate that to what is happening in your application.

How are your processors faring ? Is the system load high? What's causing that?

Do you you have high I/O Wait values? Why?

Are your queries optimised ? Do you have proper indexing ? Have you checked for long running queries ?

  • switching from Apache httpd to Nginx might be the right thing to do once you have fully analysed the situation and made that decision but until you have done that answers like this seem more religious than scientific. – user9517 Dec 30 '16 at 14:55

Its probably PHP limited. In that case nginx won't help. You can use Varnish in combination with the Turpentine addon to make catalog pages a lot faster. That solves 90% of your load. Checkout will still be slow though.
