Reports are run against the collected data (nfdump files). The larger the
time interval, the more files nfdump has to process. For my system, I
collect about 4 days worth of netflow data, and they take up ~170GB of disk
space. If I run a top x report on the whole interval, it will take up to an
hour to process.
Sadly, during this time nfdump is not returning any data (since it is still
chewing on the problem), so your browser/firewall/proxy might conclude that
the host is not responding and reset the session.
