One of the most common questions when switching to a vServer is: how much RAM and how many CPU cores do I actually need? Too few resources slow your project down; too many cost unnecessary money. In this practical guide, we show you how to find the right vServer for your use case.
An undersized vServer leads to slow load times, timeouts during traffic spikes, and in the worst case, outages. An oversized vServer, on the other hand, causes unnecessary costs for resources that are never used. The good news: with most providers – including Speed-Net – a vServer can be upgraded easily at any time, so you don't have to plan everything perfectly from the start.
For a static website, a small landing page, or your first experiments with your own root server, 2 GB of RAM and 2 cores are usually completely sufficient.
A typical WordPress project with moderate traffic runs comfortably on 4 GB of RAM. With several plugins, high visitor numbers, or additional caching, it's worth having more headroom.
Shop systems like WooCommerce or Shopware process significantly more dynamic requests, especially during cart and checkout processes. Here, at least 6 GB of RAM and 4 cores are recommended, particularly during seasonal peaks like Black Friday.
Anyone running several services at once – for example Docker containers, a database, and an application in parallel – should plan more generously and go for 16 GB of RAM or more, to have enough headroom for load spikes.
The number of CPU cores mainly determines how many requests your vServer can process at the same time. For individual websites, 2 cores are usually enough. As soon as several applications run in parallel, or your website needs to handle many simultaneous visitors, 4 to 6 cores are worthwhile to avoid bottlenecks.
Both strategies have their merits. If you can reliably estimate your project's future development, it's ideal to plan with some headroom. If you're unsure, start with a smaller, cheaper package and move up a level easily as demand grows – without any data loss or long downtime.
"Our recommendation: plan realistically for your current needs and upgrade as you grow, rather than oversizing significantly from the start."
The right size for your vServer depends heavily on your specific use case – from 2 GB of RAM for small projects to 16 GB or more for demanding setups with several applications. Thanks to easy upgrades, you don't have to commit to everything from day one.
