A few years ago a fully-dedicated 100Mbps up-link for a dedicated server was a dream for many folks. Not anymore! The bandwidth pricing went down drastically, the internet connectivity speed has increased a lot. Nowadays even a budget dedicated server has 100 Mbps up-link and the question is how much bandwidth you can push? Let’s [...]

Remember the time when 50GB monthly traffic for a dedicated server was so much bandwidth. Nowadays, 1000GB, 3000GB or even higher traffic monthly limits are common, but there are quite a few dedicated server companies lately offering 10TB (10000GB) monthly traffic limit. This is quite a huge monthly limit and 99%+ web sites will never [...]

Some hosting services are just, plainly put, bad yet others simply suffer from issues with bandwidth and reliability.

By default Centos, RedHat and Fedora starts multiple daemons that are actually not needed, for example: nfs nfslock cups gpm and I am suggesting you disable these services asap. You can turn it off via chkconfig command or even remove from the execution at init levels as well. chkconfig –del cups chkconfig –level 3 cups [...]

My personal choice is Cpanel – it’s somehow more friendly for me and has a lot of more features. However, DirectAdmin requires less resources from my own experience.
