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
Thu Dec 1 13:50:31 EST 2005
-----------
HTT enabled:
-----------
# date; for i in 1 2 3 4 5; do super-smack select-key-mysql.smack 10 1000 |
grep select_index; done; date
Wed Nov 30 22:47:26 EST 2005
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
Wed Nov 30 22:47:33 EST 2005
-----------
For linuxthreads and libpthread, the numbers are all within the same margin
as the other post as well.
Cheers

Would you have a try of disabling HTT? It harms performance for
certain applications.
