Hi all,


I am developing an application using PHP - Mysql and memcached (for


I wanted to know more about the chunk size growth factor which is set to
1.25 by default.

We change this by using the -f option.


What does this factor mean?

What exactly will happen if we increase it?

Will this increase the slab size to more than 1 MB?

What all values can be set to this (1.25, 1.50, etc.)

I have set the chunk size to 32 KB in the PHP memcache client.


Thanks in advance.
