In this article we have summarized useful information about Next Level Hosting.

What is Next Level Hosting?

"Next Level Hosting" is the generic term for our current generation of Linux hosting tariffs. The most important innovation is the Performance Level feature, with which you can now react flexibly and quickly to increasing performance requirements of your websites at any time without having to change tariffs.

What is the performance level?

The performance level indicates how many resources are available to your hosting package to run PHP-based websites and applications. The higher the level, the more performance reserves are available to avoid performance bottlenecks.

You can react flexibly to growing visitor numbers or other requirements of your websites, because the performance level can be changed at any time and is not bound to a certain tariff.

Each level is assigned different performance values that are important for the execution of PHP scripts. For example, the PHP scripts can occupy up to 2.5 GB RAM in the web server's RAM at level 1, but up to 19 GB RAM at level 5.

Performance Level Features (PHP script limits)

Level 1 Level 2 Level 3 Level 4 Level 5  
Recommended for a standard website with several subpages Well-visited blog with regularly updated content Complex website with daily updated content Several performance-intensive websites or a well-attended Internet forum Online shop with a large product portfolio and a high number of visitors.  
RAM up to 2.5 GB up to 6 GB up to 9 GB up to 15 GB up to 19 GB
Processes per minute 300 600 900 1200 1500
Memory Limit 512M 640M 640M 768M 768M
  • RAM: The maximum amount of memory that PHP processes can use simultaneously. This value is calculated as follows: RAM=Memory_Limit*max_parallel_processes

  • Processes per minute: Gives information about how many PHP processes can be processed per minute on average, without waiting times occurring or processes having to be terminated due to a runtime overrun.

  • Memory Limit: The maximum amount of memory that can be used by individual PHP processes.

What are PHP scripts and how do they relate to the above performance values?

PHP is the most commonly used programming language for creating websites. For example, the popular Content Management Systems (CMS) WordPress, Joomla and Drupal are completely written in PHP. The higher the performance level, the more power reserves are available to avoid unwanted delays in loading and page layout, depending on the number of visitors.

What rates can I use the performance level with?

To adjust the performance of your package using Performance Level, you need a current Linux hosting plan of type Webhosting Business or higher.

  • This applies to existing packages if you have reordered the contract as of 03/23/2017 or have changed the rate after this date.

  • The performance level of the tariff cannot be adjusted. However, you can switch to one of the tariffs listed in the table at any time.

The following table shows you which tariff contains which performance level as an included service:

My rate has no performance level - what can I do?

You can switch to a current Next Level Hosting plan at any time within the Next Level Hosting plans or from an older plan. Here's how

How do I change the performance level?

You can adjust the performance level in your 1&1 IONOS at any time. To do this, click on Performance Level in the left menu and then order the desired level. Show instructions

Which performance level is recommended for my website?

Unfortunately, this question cannot be answered in a generally satisfactory way, as the resulting speed of a website depends on various factors. For example, it's not just how complex the pages of your website are and how often visitors visit your pages; as the number of visitors increases, it's increasingly important how well your website's program code is optimized for performance and where and how often content is stored and loaded. However, in the table above on the performance levels, we have tried to give you an orientation guide to get started.

Once your website is up and running, the performance statistics of your 1&1 IONOS gives you information on the extent to which your current performance level is working at full capacity. Depending on the degree of utilization, you will also find recommendations for changing the performance level there. If your performance level is repeatedly very busy, we will automatically inform you by email.

I have increased my performance level, but my website is not faster - why?

If upgrading your performance level does not have the desired effect, please note the following:

  • The evaluation in your 1&1 IONOS shows the utilization of the last 7 days. Effects can therefore only be observed there on the following day.

  • Besides the performance level, the following factors can influence the performance of your website: Database

    If a lot of data is read from a MySQL database or information is stored on frequently visited pages, the database server may no longer be able to provide this data quickly enough. I/O

    performance of the web space:
    If more extensive static content (e.g. images) is frequently loaded from the web space or data is continuously written to the web space (e.g. log files), this can impair the loading and reaction speed of your website.

How and when will I be charged for the ordered performance level? What happens if I change again?

For technical reasons, the performance level is calculated separately from your contract. You will therefore receive a separate invoice for the monthly amount shown in the 1&1 IONOS (of course, this will only be charged if you raise it above the amount in your rate including level). The amount is always debited in advance.

If you order another level, the calculation process starts again. Amounts previously paid will be credited to you pro rata with your next contract invoice.
