Load Balancing Script

Load balance on the mikrotik is a technique to distribute the traffic load on two or more lines in a balanced connection, so that traffic can run optimally, maximize throughput, minimize response times and avoid overload on one connection path.
During this time many of us who think wrong, that by using loadbalance two connection lines, then the greater the bandwidth that we will get a doubling of bandwidth before using loadbalance (accumulation of both the bandwidth). This needs to be clear first, that loadbalance will not add much bandwidth we get, but it only served to split the traffic from both the bandwidth so they can be used in a balanced manner.
