A larger number of ActiveConns indicates a machine which is slower to
respond (that is, these connections have not reached TIME_WAIT or
FIN_WAIT), or a machine which has KeepAlive switched on in Apache.
Of more significance to you during testing would be:
ipvsadm -L -n --stats
ipvsadm -L -n --rate
If you use the "watch" utility you can watch these in real time:
watch -n1 -- "ipvsadm -L -n --stats; echo; echo; ipvsadm -L -n --rate"
BTW I presume you meant "lc" scheduler rather than "ll"?
