Prestashop 1.6.1.7 very very slow

[hanisnl]

Hello everybody .

I manage a Prestashop 1.6.1.7 .... since a couple of weeks ago, the website is veeeeeery very very slow .
It takes 10-12 seconds for the browser to receive a 25kb html file ... once that loads, everything else loads super fast, as it should .

I did try about everything that I know ... the hosting is really good (a lot of resources / extreme ssd / etc) ... everything is up to date ... and it worked really good until a few weeks back .

When I empty the Cache .. for a couple of minutes it seems to work a little better.

BUT ... randomly .. from time to time .. I get errors in my error_log that smarty cache was unable to write to file .. totally random .

 

There are a few errors, that also appear to be totally random and I never saw them before :

[20-Oct-2016] PHP Fatal error: Uncaught exception 'UnexpectedValueException' with message 'RecursiveDirectoryIterator::__construct(/home/mainwebsite/cache/smarty/cache/af/d2): failed to open dir: No such file or directory' in /home/mainwebsite/tools/smarty/sysplugins/smarty_internal_cacheresource_file.php:196
Stack trace:

#5 / in /home/mainwebsite/tools/smarty/sysplugins/smarty_internal_cacheresource_file.php on line 196

I also did a DEBUG PROFILE .... but I didn't really find info that could help me fix the situation .

How can i further debug the issue and find out what the heck is making the website load so slow ??

What could be the problem ?

Thanks !

Anyone !?

too bad no one answered ... but the problem was from the hosting account .. support from hosting helped me with the RecursiveDirectoryIterator problem .
