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.
