I’m thinking the default value may actually be 128M. That applies to the maximum amount of memory that a php script is allowed to consume, as defined in php.ini:
memory_limit = 128M
Are we both referring to the same setting?
Oh yes I am sorry… I was meaning 256MB… I have increased wp memory to 256…
I have increased wp memory to 256.
You aren’t increasing WP memory. You’re increasing the maximum amount of memory that PHP will allow any script to consume before it errors.
You might leave it at 256M and continue monitoring things. I think 10G sounds a bit excessive, and it isn’t going to increase your site performance. Could you imagine having a run-away script tat just kept chewing away until it ate up 10GB of memory? Yikes..
High Traffic Tips For WordPress
Yes I think you are right!
So my websites “slow down” and even “down time” (when 500+ users are active) It’s not caused from memory limit…
Ok, now I have to check the server condition, or the website theme or plugins performance… Right?
Can you give me some tips for checking what is going wrong? Thanks!
