Hello guys, normally, I try to avoid advertising my linux distribution in non-commercial mailing lists (even though it's 100% open source), but yesterday's story amazed me so much that I simply have to. What happened yesterday? My largest customer switched from multiplexed DSL-Lines (copper) to optics, and I did some quick measurements on the performance of Route Hat. Admitedly, they are not very thorough, but I can do that as well when I have more time. Site specs: - LAN consisting of 5 dormitories totalling ~1400 computers (max measured concurrent users ~750, at the time the measurements were done there were slightly over 500 concurrent users) - 6 subnets - 16MBit internet (16 up, 16 down) Router HW specs: - Athlon XP, 2GHz - 512MB RAM - 40GB HDD (only ~100MB used, mostly for logs) - 2* 3Com PCI 3c905C Tornado (you see, nothing special) Router SW specs: - Route Hat 0.3.193 (built 2. may 2005) - all functions active except DHCP-Server (customer has its own), mainly: DNS, NAT, firewall, bandwidth management, user management (IP+MAC matching), ip accounting, transparent smtp proxy with a/v, checking for unpatched windowses (vulncheck.pl, see here: http://cert.uni-stuttgart.de/archive/bugtraq/2004/05/msg00228.html) and some other experimental security programs - user list polled from external data source (postgres) provided by customer Active measurements (from a normal machine located in LAN): - average RTT (ping) to next hop (provider's router): 20ms, packet loss 0.1% - RTT jumps over 100ms in only 0.03% of the monitored packets. - loading of webpage from heise.de (used because they have blazingly fast webservers): 200ms - download of kernel 2.6.12 from gd.tuwien.ac.at (44,5MB): average 208kB/s Passive measurements (on the router, averages): - Router system load - under 0.01 - Router CPU utilisation - under 0.1% - Forwarding pps: ca 3500 in each direction - Outgoing Bandwidth utilisation: 98% - Incoming Bandwidth utilisation: 91% (I think I still have a reserve here) Anyone is of course free to download it and try for themselves :-). PS. Don't expect me to respond to anything until next Friday, I have exams. Yours sincerely, Peter _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
