We are looking to upgrade our current SQL and Server, at the minute a lot of our larger tables (2-3 million rows) are timing out when I attempt to do simply queries such as selecting the transactions from the current year. We currently have a 6 year old server, could the timing out be due to the number of the rows? I have just looked and the server only has 4 GB of RAM would increasing this allow for more Memory to process the query as well as the whole running of the server? Or would it be simpier and more effective to get a new Server and keep the old as a backup or File Server? Or is there a better method?
