Joomla Ram requirements

[bobby11]

Hi there,
I have recently switched from shared hosting to cloudbased hosting with my joomla websites...
I have nearly 130 sites, half of them are simple business card websites others are bigger, and nearly 30 of them are "about 4.000 pages" each...

on shared hosting I got no issues in terms of hardware performance, but in cloud hosting I have RAM issues....

my current cloud server configuration is 4 cpu/12gb ram - and since my projects are not high CPU intensive 4 is ok but RAM is continuously going out of memory...

My questions is, how much RAM memory does one joomla installation requires?
Maybe in my case would be better to maintain shared hosting since for larger projects?

thank you

My questions is, how much RAM memory does one joomla installation requires?

The amount of RAM needed for a website depends on a lot of variables.
Do you use memory caching like REDIS or Memcached?

[Per Yngve Berg]

What limit have you set in php (128M, 256M or 512M)?

Note that this is for each request. With 4 concurrent users and 256M, 1G will be used on the server.

Hi there, yeap Memcached is installed...

Hi, thank you for this suggestion actually I see each website has default configuration o 640mb as standard for "php memory limit" I have asked my host if these could be the reason of the issue (and I suppose it may be) will provide some configuration tests in order to find best configuration for my case

[Per Yngve Berg]

128M will be sufficient for most sites. Enable debug in Global Configuration and check what memory the page is using. Joomla will show a "trying to allocate xxxM of ram, using yyyM" when going out of memory.

It sounds like the toatal 12G on the server is depleted rather than the limit of a single site.

Have you thought about changing from memcache to file cache. Then the memory consumption would decrease. For my own Joomla site excluding bad bots in htaccess did decrease memory consumption considerable. If you have Cpanel you can look for robots and last visit in Awstats. How much they consume in GB.
