That's good news.
The details in my case are
NIC/driver fxp
Device polling No
OS 4.8-RELEASE-p13
Hardware p5/166 Mhz/slow FSB/slow RAM
bandwidth <= 128 kbps (ethernet port
of WAN router, filtered for off
LAN traffic)
CPU usage 30-50% when there is a file
copy (scp of a 1-2 MB file)
ntop CVS from 17 Oct 2003
Other notes ntop 2.2 on same hardware/OS
does use more than 20% CPU -
when daemonising - and not
when there are traffic flows
far greater than this.
Is there any chance of your trying RELENG_4_8 (4.8-RELEASE-p13) ?
In view of the age of my ntop platforms (reused terminal servers) and
the problems with the ata driver (shudder) I was hoping to wait a good
long time before going to 4.9-RELEASE.
Yours sincerely.
