Good afternoon.
1) Installed Memcached, then Memcached PHP Extension.
What are the best settings you need to set in file etc/sysconfig/memcached:
PORT="11211" USER="memcached" MAXCONN=" CACHESIZE=" OPTIONS="
If the memory on the VPS:

On the website, the manual I used was the following:
MAXCONN="2048" Maximum number of connections
CACHESIZE="4096" the Amount of actual RAM on the server
And by analogy I put MAXCONN = 25000, CACHESIZE = 50000. Right?
2) How can I make sure that memcache and memcached PHP, everything is normal cacheroot? Maybe the team is there for ssh or a particular directory, where you can watch...
Thanks in advance.
