Your 808gps server must be added with a function that monitors the performance of the GPS server, at least you can track the maximum concurrency that your server can currently bear, the Inbound speed of your GPS server, Alarm Analysis for latency, and various error logs that may occur under pressure bottlenecks.

This is a creation in Article, where the information may have evolved or changed. Recently, in a colleague's question: when iterating over a slice, it would be better to move the loop condition out of the loop for len than the Golang compiler's optimization results. That func G0(a []int) int { L := Len(a) for I := 0; I L; I++ { } return 1} Whether it will be better than func G1(a []int) int { for I := 0; I Len(a); I++ { } return 1} Results are more optimized (currently t

prediction based on dynamic model can reduce the search scope, so it can improve the effectiveness and robustness of tracking. Improvements to these sections will further improve the existing technology of online target tracking algorithms.The results show a significant improvement in the target tracking area over the past decade. We present and demonstrate the evaluation criteria for in-depth analysis of tracking algorithms from multiple aspects. These numerous performance evaluations help to
