I used Dreamhost VPS before, used Burst.net VPS. Now I am going to introduce Linode VPS service.
Linode provides XEN VPS only. It upgraded VPS service to the new generation. Let me summery it then you know how better it is.
Storage increased by 20%:
- Linode 512 goes from 20GB to 24GB
- Linode 1GB goes from 40GB to 48GB
- Linode 2GB goes from 80GB to 96GB
- Linode 4GB goes from 160GB to 192GB
- Linode 8GB goes from 320GB to 384GB
- Linode 12GB goes from 480GB to 576GB
- Linode 20GB goes from 800GB to 960GB
Linode NextGen: The Network X10
- Linode 512 upgraded from 200GB to 2000GB (2TB)
- Linode 1G upgraded from 400GB to 4000GB (4TB)
- Linode 2G upgraded from 800GB to 8000GB (8TB)
- Linode 4G upgraded from 1600GB to 16000GB (16TB)
- Linode 8G upgraded from 2000GB to 20000GB (20TB)
Linode NextGen: The Hardware
- Powering our NextGen hosts are two Intel Sandy Bridge E5-2670 processors. The E5-2670 is at the high end of the power-price-performance ratio. Each E5-2670 enjoys 20 MB of cache and has 8 cores running at 2.6 Ghz.

When use VOIP service with a VOIP adapter, you have to choose the codec.
The codec is very important. Unsuitable codec will make your call intermittently.
Codecs are settings used to fine-tune the audio compression of your VoIP devices.
Different codec needs different bandwidth.
The following protocol header assumptions are used for the calculations:
40 bytes for IP (20 bytes) / User Datagram Protocol (UDP) (8 bytes) / Real-Time Transport Protocol (RTP) (12 bytes) headers.
Compressed Real-Time Protocol (cRTP) reduces the IP/UDP/RTP headers to 2or 4bytes (cRTP is not available over Ethernet).
6 bytes for Multilink Point-to-Point Protocol (MP) or Frame Relay Forum (FRF).12 Layer 2 (L2) header.
1 byte for the end-of-frame flag on MP and Frame Relay frames.
18 bytes for Ethernet L2 headers, including 4 bytes of Frame Check Sequence (FCS) or Cyclic Redundancy Check (CRC).
So the most used often protocol/codec are listed below.
Codec Name – Bandwidth Ethernet (Kbps)
G.711 (64 Kbps) – 87.2 Kbps
G.729 (8 Kbps) – 31.2 Kbps
G.726 (32 Kbps) – 55.2 Kbps
G.728 (16 Kbps) – 31.5 Kbps
So, if you use two computer and one game palyer, or Wii, and the Voip Adapter in the same home network, you’d better set codec to G.729 to save the bandwidth and get better voice quality.
If you want to add bandwidth throttling on any one site, please follow my steps below:
1) Login your control panel of dreamhost. https://panel.dreamhost.com
2) Under main menu on the left side, click status.
3) Then click Bandwidth Usage. There is a list of your site per domain.
4) Click enable to enable bandwidth throttling with your own settings.
I have a 2TB Bandwidth usage capacity.
Currently I have a very small blog for my daughter, Grace. So, I give the limit to 30GB per month.
Dreamhost’s default setting is disable of bandwidth throttling. It will cost you much if you use over the limit. $1 per GB over.
