Do we still care about HZ=1000 with dummynet ?

[Ensel Sharon]

I see in the dummynet man page:

     Generally, the following options are required:

           options IPFIREWALL
           options DUMMYNET
           options HZ=1000         # strongly recommended

But all of the NOTES and other documentation only mention setting the HZ
value in conjunction with DEVICE_POLLING.

The man page for dummynet is dated October 2002.

So the question is: circa 6.1, does it matter anymore to set an HZ value
if you aren't using DEVICE_POLLING ?

If so, why ?  I understand the benefit when used with DEVICE_POLLING, but
not for dummynet ...

Thanks!
