[SA-exim] SA and Server spec recommendations

[Odhiambo Washington]

Helo local_scannners,

I am running SA (Exim-4.10) and thanks Marc, the installation was quite painless.
I used method 1 - replace src/local_scan.c.


I installed SA (local-scan) last night and apart from the fact that I am still
familiarizing myself with it's actions, I do realize that the loads on my server
had increased tremendously. Without it, my load averages were in the 0. range.
Now I see it's in the range of between 4.x to 10.x (sometimes) - this server I
use is the our "beast of burden". This is what I see since last night and there
is no indicator that it's ever gonna go down ;-)

Does running SA (in conjunction with other services - httpd, mysqld, POP3 daemon)
generally requite higher system specs??
Maybe yes, but the main reason for my asking this is to tap on your experiences
running SA at your sites.


Thanks in advance.
