about mirroring port

hello, all.

I would like to setup ids(like snort) at mirroring port in cisco catalyst switch.
but all of the network traffic is over 100M, and my linux server which installs snort is not so good hardware.

So I think that when I setup snort at mirroring port, all traffic should via linux server so the network speed would be slow

Question.

1. when I setup the mirroring port,all traffic(for example, port2 traffic) would transfer like this or just copy the traffic mirroring port too?

 (1) client --> mirroring port1 --> port 2  
 (2) client --> port 2


            --> mirroring port (copy too)

2. Is there any problem when I set snort at mirroring port if the traffic is so high(over 100~200M)?  

3. do you know any commands to setup mirroring port at catalyst 400x(catos based) switch?

Thanks in advance.
