Although this seems a straightforward question, estimating the exact number of visitors a hosting account can support is a complex task as it depends on various factors. This includes the efficiency of your website’s code, the type of content you serve, the complexity of database queries, and the overall optimization of your site.
The short answer is that GreenGeeks does not directly limit the number of simultaneous visitors.
Instead of limiting visitors, each account’s assigned a finite amount of physical resources(CPU/MEM/IO), and each HTTP request takes a certain amount of resources to complete.
Additional factors like traffic patterns and visitor behavior can vary, impacting resource consumption.
Each time a visitor accesses your website, the hosting server must process various tasks, such as serving web pages, reading the htaccess file, executing scripts, handling database queries, and more.
These tasks require CPU, Memory, and Disk IO resources to complete, allocated from the fixed amount of resources assigned to the hosting account.
Since physical resources get shared among the domains in the server itself, including addon domains, aliases & sub-domains, it’s possible for one site to be using all of the available resources for that account.
If your hosting account has insufficient resources to handle the number of requests, it may lead to slower response times or website downtime, including 508 errors.
Resource Usage Monitor
You can monitor the resource usage on your account using the Resource Usage tool in cPanel, under the Metrics heading; this will show the resource usage over time, including any “faults” or errors.
Optimization is often the primary factor in determining how many simultaneous visitors the hosting account can support, as optimization allows more visitors to access your website without straining your hosting account’s resources.
By optimizing your website, you can improve its overall performance and efficiency, thereby reducing the resource consumption required to serve each visitor. This allows your hosting account to accommodate a higher number of simultaneous visitors compared to the unoptimized site.
Here are a few ways in which optimization can help:
- Code optimization: Optimizing your website’s code involves streamlining and refining the underlying programming to make it more efficient. The code optimization process can include minimizing redundant code, optimizing database queries, and employing caching techniques. By reducing the complexity of your code, it will run faster and allow your hosting account to handle more visitors with the same allocated resources.
- Image and file optimization: Large images and files can significantly slow down your website’s loading times and consume additional bandwidth. Images can be optimized via resizing, compression, or conversion to another format like WebP, resulting in significant savings without significant quality loss.
- Caching mechanisms: Implementing mechanisms for server-side caching to store static versions of your web pages or frequently accessed data is critical to maximizing the number of visitors your account can support. Static server-side caches reduce the need to generate content dynamically for each visitor resulting in faster response times and lower CPU, MEM, and IO usage, allowing more visitors in total.
- Content delivery networks (CDNs): CDNs distribute your website’s static content across multiple servers worldwide, reducing the load on your hosting account’s server and improving the delivery speed for visitors in different locations. By offloading the delivery of static files to the CDN, your hosting account can focus its resources on dynamic content, enabling it to handle more visitors simultaneously.
- Database optimization: If your website relies heavily on database interactions, in addition to caching, optimizing your database structure, indexing, and queries can significantly enhance performance. Efficiently accessing and retrieving database records reduces CPU and MEM usage overall.
It’s important to note that optimization alone has limits, and the resources allocated to your hosting account ultimately play a significant role in determining the maximum number of visitors it can support.
Calculating Visitor Capacity
Monitor the resource usage of your website to get an idea of the visitor capacity. Aside from the built-in tools, third-party plugins like Query Monitor for WordPress can examine how each component impacts the overall site.
Keep an eye on CPU and memory usage during periods of high traffic to understand the average resources consumed per visitor.
Once you’ve determined approximately the amount of resources required for each visitor, it’s possible to do a rough calculation of the total number of visitors supported by the account.
For example, if your hosting account has 2 GB of memory and you determine that your website uses approximately 100MB per visitor, you can calculate that 2GB / 100MB = ~20 Visitors.
Remember that this calculation provides an estimation based on average resource usage per visitor. Actual visitor capacity may vary depending on factors like traffic patterns, visitor behavior, and the efficiency of your website’s code.
If you have any further questions about how resources affect the number of visitors that can visit the site simultaneously, or how optimization can increase visitor capacity, please open a Support Ticket Request within your GreenGeeks Dashboard, and the GreenGeeks Technical Support Team will be glad to assist you.
