Beta Branch add PHP_TUNING variable and phptuning function

All my servers though uses this formula Eva.

 

I use also dynamic on my servers and a bit higher values than that formula

@Revenge

may have some nice formula for this as he did also some Dddos tests and maybe knows the limits better ?

 

If you have a powerful CPU, like having 4ghz clock speed.
And database server outside localhost.
It's safe to increase it to:

 

My formula looks like:

Code:

pm = dynamic
pm.max_children = cpu x 5
pm.start_servers = cpu x 2
pm.min_spare_servers = cpu x 1
pm.max_spare_servers = cpu x 5

 

Also i would like to confirm that if we set PHP_TUNING='y' it will be triggered at:

1)Php upgrade
2)Php downgrade
3)Php upgrade or downgrade and ask YES to overwrite existing phpfpm config
4)Php upgrade or downgrade and ask NO to overwrite existing phpfpm config

?

 

Guys, where do you take those values from? You monitor your server, change the values and test the use of CPU/memory/disk until you get the best results?

Based on years of experience using PHP-FPM.
Tuning based on the website needs.

Yes always.

PHP-FPM mostly matters on CPU only, not much on Memory.

 

How do you know what your "website needs"?
I'm currently importing a forum and similar values like yours provided better results (faster import) than pamamolf values.

 

What is your CPU model?

 

To prevent CPU on overloading on heavy PHP-FPM task I'm using this:

Code:

pm = dynamic
pm.max_children = cpu x 3
pm.start_servers = cpu x 1
pm.min_spare_servers = cpu / 2
pm.max_spare_servers = cpu x 2

 

I thought that pm.max_spare_servers should be equal to pm.max_children or not?

 

Ok thanks

That seems confusing to me.....

Setting for example:

How many will be available as standby?

Or is it like the amount of spare servers must be between 5-10 and no more or less?

 

Now i think i got it

So if it goes under 5 it will respawn some and if more than 10 it will kill some....

 

@RoldanLT

What formula do you recommend for a cpu like:

2X Intel(R) Xeon(R) CPU E5-2640 v3

32
