Is Memcached suitable for my RSS Agggregator site?

[dewaphp]

Hi Folks,

 

I am in the process of developing an online RSS aggregator site, http://www.kedoya.com . The site is currently in beta stage and is painfully slow due to large database. Due to its nature, Kedoya database grow by 10 MB everyday and will be 4 GB in size by the end of this year.

 

My questions are :

 

- Is memcached suitable for Kedoya.com ?

- What is the maximum size of database table that can be effectively handled by memcached?

- Assuming I have a dedicated server with 20 GB of RAM, can I split a big 16 GB table into 4 memcached tables (4 GB each) ?

- Assuming I have a dedicated server with 20 GB of RAM, can I load 4 big tables (4 GB each) into 4 memcached tables (4 GB each) ?

 

thanks a million!
