Ok, thank you. I am just trying to undersatand why a same query, in a same graph, has very different query times in each execution. Sometimes starts with 4000 ms, and when I run again decreese to 200 ms. I am using neo in my doctor degree thesis. I need to measure queries times in graphs with 1000, 5000, 1000 and 50000 nodes. I cant get a precise time. Each run has a time, and they are very different. In java the times are longer, and graphs with very different sizes have very similar times for the same query. I am looking for more precisely form to measure queries times. Thnak you again.
