Often we hear news of slow systems. One reason is that the generation of data is higher now. Nowadays it is common the user to post files, photos and videos, but different technologies not always deliver the same performance. This research simulates ten scenarios and points out between two tools, Node.js and Apache Tomcat. Results of this research show which has best measures latency, latency variability and efficiency of use CPU, if used as Middleware to upload. It is reported here this measures and it indicate as metric, to monitor the latency variability through the switching processes in the CPU.
