Nutch performance

[Anton Potekhin <an...@orbita1.ru>]

Hello! i would like to know how many pages can nutch index daily and how 
many searches can it handle. I understand that it depends on the 
hardware because i want to know not exact results ;-).  For example  i 
will use 4 servers.
And i will use the following configuration:
1) server1 i will use for Jobtracker, namenode
2) server2 i will use for the first Tasktracker and the second DateNode
2) server3 i will use for the second Tasktracker and the second DateNode
2) server4 i will use for tomcat for searching

How many pages can i index daily and how many searches can this 
configuration handle?

I realize a lot of this depends on the hardware but in general what would you say. 
And what can you say what i must change in this configuration? 
And what hardware do you recommend to use for each server?
