FreeBSD 6.0 MySQL Performance

I use databases/mysql50-{client,server} and use benchmarks/super-smack to test. There are 3*2*2*2 = 24 cases:

• Compile options: none, WITH_PROC_SCOPE_PTH=yes, WITH_LINUXTHREADS=yes
• /etc/libmap.conf: none (libpthread), libthr
• kern.timecounter.choice: ACPI-fast, TSC
• kernel: ULE+PREEMPTION, ULE

These benchmarking were tested on my laptop (IBM x31 2672-IQV, Pentium-M 1.5G with 512MB RAM), and powerd was disabled. Detail informations (dmesg, sysctl, and kernel config file) will post later.

The commands are:

for i in 1 2 3 4 5; do super-smack select-key.smack 10 1000 | grep select_index; done
for i in 1 2 3 4 5; do super-smack update-select.smack 10 1000 | grep select_index; done
