Design questions...Right now, I am having a single Win 2k server which I do web development from (P3 400, 128 RAM) 
which is also running snort to monitor two T-1 lines and a 10 mbps network of about 25 systems.  It is logging to its 
MSSQL installation.  Believe it or not, it's actually handling all the traffic pretty flawlessly.  I do have to reboot 
it every few days as Snort and MSSQL slowly but surely seem to consume my page file (memory leak?  not sure).

IMO, I'd give it a shot.  The two T-1 lines would be no problem for a modern dedicated machine to keep up with.  The 
100 mbps networks, I honestly don't know.   If it's doing nothing but running snort, I'm betting it would handle it.  
Take what ya can get and give it a try :D

  Hi, hopefully, my email is sorted out now and this will get through... 
  I have some performance questions that I hope that someone would be able to help me out with. 
  I am trying to convince my boss to start implementing snort at a serious level. Problem is, he is a windows/closed 
source type of guy and I am a unix/open source type of guy. I am trying to convince him to buy seperate boxes for each 
of the sensors and then a logging box that has its own private network to send data across. Ideally, I would have 4 
snort sensors and one of them be an ACID/PHP/MySQL log server. He does not want to pay for all the boxes because he 
thinks that they are going to cost $2.5k a pop. I think that we can go with a non major vendor (pogo linux, penguin 
computing, etc....) and get it cheaper, but that is a different story. 

  So, he brought up the idea of having one big box and having multiple nics. Now, I know that this can easily be done 
using multiple snort processes/conf files/etc... However, I am wondering about the performance of such a beast. What 
type of horsepower do I need to monitor 2 T1s (on seperate networks) and 2 100MB networks (also seperate)? Also, it 
will probably be running the database as well, on a seperate network. Can people give me an idea of what they are 
running out there? 

  Thanks!
