Some of the bandwidth control settings are not working

#1
Bandwidth and MinBandwidth does not work.
I am currently using LiteSpeed Enterprise 5.4.8.

I configured Bandwidth in Configuration > Virtual Host Template > General > Apache Style Configurations.
BandWidth 192.168.1.2 50000
I thought that the bandwidth allotted a specific IP would be 500KB/s
But I measured transfer rate in ab and it was 115000 KB/s.

$ ab -c 1 -n 1 https://hoge.jp/testfile

I configured MinBandwidth in Configuration > Virtual Host Template > General > Apache Style Configurations.
BandWidth all 50000 MinBandWidth all -1
I thought the maximum speed per client would be 500KB/s.
But I measured transfer rate in ab and it was 115000 KB/s.


I can't get these two setting items to work, am I setting them up incorrectly?
