It depends entirely upon the developers. Well-written code and well-cached displays seldom have performance or display issues.

We did sometimes encounter stability issues with a few modules, but hardly ever with the core of Drupal itself.

I have not really experienced any stability issues with the Drupal core. In some cases, we found some issues in the contributed modules. However, these bugs usually already have a patch available. If a patch doesn't exist, then we try to fix it and contribute back.

The Drupal core is really stable. Depending on the community modules you are using, you may encounter some stability issues.

As a free product, you have to look for a solution to an issue yourself. The community is big. You often see that someone else has found the solution and posted it publicly. Everything is integrated into the product very fast.

Drupal Version 8 is a more or less mature product, since it was launched more than one year ago.

However, when combined with custom implementations and contributed modules, some things seem not stable. Being an open source solution with a large community, it is easy to find a patch or a workaround. However, this requires some knowledge.

There were only JavaScript conflicts. This is especially the case if you use lots of modules that utilize JavaScript.

Until now, we have not experienced any stability issues. Drupal has regular security, feature updates, and the Drupal community is always there for any kind of support that you might need.

Stability is often a concern for large scale deployments, and Drupal can handle those - but expertise in Drupal coding standards, and front end performance are at the forefront of creating a stable environment. Outside of human knowledge, Drupal itself has some great caching functionality included in its core. Page caching and compression, CSS and JavaScript compression and aggregation are also included in core functionality as well. View full review »

Customization, such as code introduced outside of the core and contributed functionality, that is introduced, can cause instability.

Like in most of the successful trending tools, the same things that make Drupal great also make it not-so-great.

For example, the fact that Drupal core and contributed code operates 'in the wild' and in front of so many users, it gives it, in effect, the benefit of the largest UAT for any CMS.

That coupled with the fact that its developer community is constantly making updates (e.g., security enhancements, support for new versions of libraries and standards, handling of edge cases, etc.), makes the documentation effort more problematic.

In fact, successful Drupal developers often use the code itself as the documentation. It helps to use the advanced debugging tools, in order to quickly understand how a particular piece of Drupal code works.

This is ironic, since the developer must then use the knowledge to write Drupal code which, as a rule, must be written generically and not tightly coupled to specific technologies.

The other thing to keep an eye out for, is that Drupal developers move too fast to resolve issues, especially the short-term consultants.

Often, organizations will employ short-term consultants at a much lower rate, than proven developers who maybe from a reputable agency or firm.

In these cases, the short-term issues/enhancements are implemented and the consultant moves on. However, more often than not, the work performed creates problems down the line because an unmaintainable approach was taken.

Thus, it is important to note that this phenomena is not unique to Drupal. Rather, Drupal's trending status, combined with the various options,that the developers have to implement the same functionality, seems to breed this type of situation very well.

Drupal 8 is only 1.5 years old. It has stability issues, but not major ones. Also, it is very important to note that the support from the community on fixing bugs is really good.

Several modules which worked well on the previous version of the product have not yet been upgraded or do not work seamlessly anymore on the newer version.
