The performance depends on how the tool is implemented. Many customers were implementing the cluster on top of virtual machines. We do not know whether the performance issues were with the virtualized storage or something else. I implement the solution for customers. My recommendation would depend on the requirements of an organization. The tool can be used for everything. It will be perfect for searching logs and files. However, the product will not be suitable for databases. I would recommend running high-performance applications for databases on top of the solution. For the ease of implementation and usability, I rate the tool an eight out of ten.
