I work for a small but growing community newspaper and we use a WordPress for our newspaper's online version. The site has been quite slow in general, especially in recent days. Our traffic has also picked up. We're using a DreamHost shared hosting plan and are considering DreamHost's private servers in order to speed things up a bit (http://dreamhostps.com/). However, we do not wish to spend more money than necessary. DreamHost PS's lowest and cheapest option is a virtual private server with 150MB of RAM and 150 MHz CPU. Is that enough to run WordPress? We plan to upgrade to 2.5 soon. We have thousands of articles (posts) stored in the database, and the front page pulls articles in from multiple sections (like a typical newspaper site does).
But I know nothing about servers and their capacity. Do you think the 150MB/150Mhz deal is a good one for WordPress? On days in which we publish new articles, we use almost 1 gig of bandwidth.
Thanks in advance for any suggestions!!
