The numbers are roughly the same with HTT disabled.  For example for libthr:

HTT disabled:
-----------
# date; for i in 1 2 3 4 5; do super-smack select-key-mysql.smack 10 1000 | 
grep select_index; done; date
Thu Dec  1 13:50:24 EST 2005
select_index    20000   1       0       14749.36
select_index    20000   0       0       14838.91
select_index    20000   0       0       14913.73
select_index    20000   2       0       14230.60
select_index    20000   1       0       14288.65

HTT enabled:

grep select_index; done; date

select_index    20000   1       0       14375.95
select_index    20000   0       0       14392.69
select_index    20000   0       0       14478.93
select_index    20000   0       0       14371.66
select_index    20000   0       0       14416.07

For linuxthreads and libpthread, the numbers are all within the same margin 
as the other post as well.

Cheers
