Not on my box. But then again, you don't really give a clue about the configuration, do you? Regardless of CPU, ntop has to do the same amount of work for each packet. But a 2.4GHz P4 is going to have a lot less trouble keeping up (and thus a lot smaller CPU% load) vs. a Pentium 166MMX
So, some comparison data is in order. (I used nntp, not ftp - it's easier to get a steady measurable load) CPU load (top): 0.7% to 1.5% Hardware: Pentium III 800 (100MHz FSB), ample free memory Configuration: running solely as a monitor (i.e. the monitoring box is NOT the NAT/Firewall/Gateway). Average network load: 1300 Kbps Network configuration: Cable Modem, capped at 1500 Kbps (so that's effectively pegged...) 2:47pm up 33 days, 20:20, 1 user, load average: 0.00, 0.00, 0.00 34 processes: 31 sleeping, 3 running, 0 zombie, 0 stopped CPU states: 1.1% user, 1.3% system, 0.0% nice, 97.4% idle Mem: 125848K av, 121280K used, 4568K free, 0K shrd, 42196K buff Swap: 257032K av, 7700K used, 249332K free 13916K cached If you are processor OR memory constrained, you are going to see a performance hit, of course... -----Burton -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Frank Raiser Sent: Saturday, June 15, 2002 12:59 PM To: [EMAIL PROTECTED] Subject: Re: [Ntop] IP displaying and more <snip /> > * While monitoring the traffic of a ftp download ntop was > using up about 20% cpu thus slowing down the ftp.

Actually the new version uses up even more CPU power. In fact it takes up to 55% of CPU thus slowing down ftp remarkably. (Didn't use the -A switch for the new version of course) -- Raiser, Frank _______________________________________________ Ntop mailing list [EMAIL PROTECTED] http://lists.ntop.org/mailman/listinfo/ntop
