Digitalocean cannot handle Magento - constant 504 error timeout

* Magento uses too many resources and constantly crashes - ERROR 504

DOMAINS : audiobuy.hk , audiodubai.ae , audiobuy.com.au , audiobuy.com.sg

Magento multi-store

SERVER SPEC (digitalocean) :
6 vCPUs , 16GB / 60GB Disk

We have contacted DigitalOcean and they say that Magento uses an "abnormal RAM and CPU resource". 

We are contacting clients advising them of Magento's resource problem , using Magento means you need to spend alot of money on a dedicated server and even then it may fail.

Advice please - we need to move away from Magento due to the resources it uses and constant downtime caused by this.

If it does connect , it takes half a minute.

Did you setup the server yourself?

Is the server properly setup and optimized properly for Magento?

What web server are you using?

What caching system are you using?

Did you tune the MySQL/Percona/MariaDB properly?
