Hi,
You may want to try running LAME with HT turned off. There are situations
where - as Paul outlined earlier - you will get non optimal memory access
patterns that cause performance to be stunted for those specific situations.
For a lengthy encoding style process the impact of HT on may be so great
that the CPU cache becomes ineffective and the negative impact on your other
work may just be to small to worry about.
You should be able to change HT in bios, reboot, benchmark and if you want
change HT back without any consequence.
There are two specific products I know of where they advise strongly to turn
HT off. MS SQL Server 2000 is one, and the other is a Beta Server class
product under NDR. From a usage perspective (IE single user, software
development) I can't say I have noticed any difference at all between HT on
and HT off for both products, but then I am not benchmarking in a true
server environment.
