Hi list,

I have two traffic shaping servers, on Linux Centos 5.5 
(2.6.18-194.32.1.el5) with HTB. In these servers are 2 gigabit NIC's and 
running script which generates two HTB class'es per ip, one for http and 
icmp, and another class for other ports. These class'es have different 
bandwidth rate. Each server serves about 5000 IP's, so each server have 
about 10000 class'es and about 40000 filters (4 filters per class), and 
all IP's are hashed with hashing tables.I am not sure that all my ip's 
are shaped. When i look to default class with "tc -s class show dev" 
sometimes default class traffic goes up, so there is asumtion that some 
of ip's are not shaped.

1. First question ist there any way to check which ip's go trough 
default HTB class ?
2. In rush hours servers reach about 975 Mbits of 1 Gbist total 
bandwidth. Question which solution is the best, buy the third server, 
and balance traffic with three servers, or buy dual or quad NIC's and 
make bond device, then start HTB on bond ? or maybe other solution ?

Thank you for the answers
