Product Manager - Healthcare Analytics at a healthcare company with 51-200 employees
QlikView is a very heavy RAM utilizer (all strong BI tools are). When we hit around 20 concurrent users, the user experience began to suffer. We contacted Qlik Support and they assisted us with a review of our infrastructure. We followed their suggestions to the tee, and were back with great speed! view full review »

In general, the solution is a little problematic in terms of scalability, as everything is stored in RAM. For more complicated analysis for many users, the memory consumption is very high and requires a lot of investment in hardware. view full review »

Data model, data size, RAM size, hardware CPUs and UI expressions / charts, are strongly related. It is possible to scale QV without problems, but the issue is more complex than not having enough RAM. Complex expressions at the UI level, single threaded object calculations, complex data models, huge data size, etc., can alter the performance of the QV application and thus we might think we need to scale. There are many tools to measure QV performance and to try keep them at an optimal level. Otherwise, if everything else is fine, we need to increase RAM. Actually, we have 1 TB RAM on our production server. view full review »

Scalability is directly proportional to RAM size & the number of concurrent users accessing the solutions. We didn't see major stability-related issues post-deployment. view full review »

I have encountered issues with scalability. We have generated models with large amounts of data and have found that the processor and memory of our server has been declining. We do not have something to help us to size the equipment requirements when a big data model is developed in QlikView. view full review »

Scalability depends on the environment and requirements. If you have large data sets, due to the in-memory nature of QlikView, the hardware needs to support your requirements. view full review »

Due to in memory technology, when datasets get really huge, rendering of graphs can take some time or even return out of memory. view full review »

The product eats all memory you give according to the number of accesses it gets, as the navigation is buffered for future queries. Ideally, the datasets must be summarized to the granularity that the public expects. view full review »
