really slow spamd scan

[Deephay <tu...@gmail.com>]

Greetings all,

I am quite new to SA (a week of SA life), and the SA is working, the
thing is, SA is incredibly slow on my server (2.8GHZ CPU + 2GB Memory
+ Qmail + Qmail-scanner).  Here's a typical scan log:

result: . 0 - SPF_PASS scantime=14.7,size=1689  .......
.....

And I have checked the SA wiki and found there is a note saying if you
are using UTF-8 locale,  the performance can be low. What I am
wondering is: Will it be that slow?
Any suggestion is appreciated.
