Regarding Memcached Server configuration?

[Ajinkya Nahar]

Hi,

 

I will be configuring memcached on a different server altogether.

My query was regarding how much memory to allocate and how do I setup the
memcached instances on that server.

 

Thanks,

Ajinkya

I am using memcached for caching purpose.

 

I have one query regarding memcached server setup as follows -

 

If we have 1.7 GB memory on a server, how much should we allocate to
memcached assuming there is nothing else running on the server.

 

Also, if we decide to allocate 1.5 GB, in that case, is it good to have just
1 memcached instance running or let's say 3 - each with 0.5 GB?

 

We are using the latest PHP memcache client which implements consistent
hashing strategy.

 

If you are only running one server, you might be better off using APC for
your caching. If you have 2 servers, you might get better performance by
running your PHP on both, and also using both for memcache (with memcache
the more physical servers you have, the faster it can go, on average). This
will also give you a bit of redundancy, letting your service continue if one
server dies.
