dear sir
i'm using NTH load balancing
when i use download manager for downloading files, internet speed is very good
but when i want to browsing internet, the speed is very low
how can i do?

no way, I think. browsing is primarily via one connection, so it cannot be received via different links to summarize speeds

yes i know it my friend
but if i have only one connection and nobody use it, then internet browsing also is very low

yessssss, it canot be faster than one of your uplinks

dear friend
my problem is that one user browsin internet very slowly when connect to mikrotik
my internet link dosn't have a problem, because when i connect internet directly to one computer, it's very fast
but when i connect internet link to mikrotik, it's very slow
it's about 15 seconds for only one web page

do you use web-proxy? are all your queues green?

dear friend
i'm not using web-proxy and queue
