Our system has potentially a few thousand firewall rules and HTB
classes. I need to find out the amount of memory these things consume:
- iptables firewall rules
- HTB classes
If anyone has any easy links to this information, that would be great.
Failing that, a pointer to a good place to look in the source code would
be very helpful.

You should not be concerned about memory load, it does not cost that much cpu load will be more noticeable bottleneck for your system in any way. as about memeory i suppose it takes about 50-100bytes each rule and up to 100 kbytes each queue like sfq. ----- Original Message ----- From: "Patrick Turley" <pturley@rocksteady.com> To: <lartc@mailman.ds9a.nl> Sent: Monday, April 19, 2004 7:09 PM Subject: [LARTC] Memory Loading> Our system has potentially a few thousand firewall rules and > HTB > classes.

Thanks for your response. Unfortunately, I *am* concerned about memory load, and I need to track down this information. The approximate numbers you suggested seem reasonable, but I need the precise answers. I don''t use SFQ at all.
