Ofcourse. But I am afraid, that my router CPU is to slow to cope with
such packet storm anyway. I will do the best I can with it, but let
us focus on Squid delay pools.

        Thanks for clarification. I expected this reasonal behavior.
And Squid seems to behave like this until initial delay-pool is
depleted.

        I'll try to do it with bare config - only basic acl and 1 delay
pool. Maybe default config is OK. If there will be any new evidence,
I'll post it.

        #670 is not specific enough to match my case. Once again:
All is OK - client loads page slowed-down to desired rate, page
is complete, everything is OK, except small-packets storm instead
of fewer big.

        I believe that. I would go for Linux, but its HW in my case
is too limited.

        I presume the same. It is a pity, I do not have direct debugging
tools to pinpoint problem myself. Hope I provided enought clues to do
this "on your side".

------------------------------------------

        The last one for today: should I end my posting to mailing list
and open new bug in Bugzilla instead? Or maybe you have added to
"to do" list already?

        Thanks again.
