Cache config

[julesork]

Hello,
I need help from community to config cache to speed up our website.
In facts, our host provider is not a specialist of magento, so I have to deal with it.
We are running a Magento Version : 1.9.1.

Here, our config :
- flat catalogue is enabled
- Lesti Full Page Cache extension is enabled
- All caches are enabled in the backend of magento
- Memcached is enabled too.

We add memcached section in local.xml and in Lesti_FPC.xml files.

After set up this config, the website is faster when a page was already hit by an user but the first display is too slow.

More, when we added memcached, we do not detect best performances.
1) is it normal ?

2 ) Could you give me some tips (easy to set up ) to speed up my website?

If you need more information, please let me know.

Thank you in advance.

Regards,
Julien

Hi,

Following those steps that you have are all reasonable - the site will be slow for the first time that any page is visited before it gets cached - there has to be one slow request before the cache can be "primed", but as long as your site is receiving visitors the popular pages should load quickly.

We have a couple of profiling guides on the iWeb sites (one on modgrind and one on diagnosing speed problems with strace) but they are really aimed at experienced Magento developers trying to use system admin tools and dedicated profilers to squeeze the last bits of performance out of the site. Maybe they will help?

Aaron

Thank you for these information, i will visit your links.

Hi,

Those profiling guides are there to help people speed up the first visit - effectively to speed up the site when the cache isn't being used,

Besides what is already mentioned, you may want to check and see if your Full Page Cache extension has cache warm up as a feature where your pages will be stored in cache before visitors even visit it.
