Next few days will test this new hosting..

I will tell you my opinion when everything will be online working.

Thanks skippy for all your help.

The most important aspect of running your server is to properly configure the services for the load you expect. I tweaked my Apache configuration a bit to make the most of my 256MB RAM. I’m _only_ running Apache2 and MySQL on this server (I moved all my email services over to Google a short while ago). I disabled unused Apache modules, tweaked the Mix and Max spare servers directive, disabled InnoDB tables from the MySQL config, etc. I’m running comfortably without dipping into swap. I think this configuration is more responsive than my previous un-tweaked VPS at TekTonic.

SliceHost publishes the stats on their machines, and their facilities:
http://www.slicehost.com/why-slicehost
They also share a number of technical articles to help you maximize your system and manage it effectively:

I think this alone sets them apart from many other VPS providers who simply say “Here’s your system. Have fun.”

As for CPU, see below for what the kernel sees. The SliceHost manager tells me I’m using zero percent of my CPU allotment, and my system reports that the load average is extremely small.

I got two questions,

1. how to check if this VPS is faster that the one i got now, i mean if i ping site that runs on Slicehost and site that runs on my VPS and the shorter time ping is on my VPS , is that mean it is faster ?

Probably CPU is important.

2. what about CPU, what CPU you got on Slicehost,

on my VPS Hypervm show that i got CPU0 1GHz and CPU1 1GHz.

I think 512MB will be ok for me, but this CPU i got now doesn’t work good in hours where i get high traffic.

There are lots of things you can do to tweak your memory consumption. First, you can use a third-party service for your DNS, rather than running it on your own server. I use EveryDNS and have been absolutely delighted with them. (SliceHost also offers DNS management, but I’ve been using EveryDNS for so long I’m loathe to switch).

I used to run my own mail services on my server, but recently switched to Google for Domains. It’s not the best solution for every situation, but I found that it did what I wanted and was one less thing for me to manage.
