OK, I have linked /etc/malloc.conf to aj, this changes the performance:

%super-smack ./select-key.smack 4 10000
Query Barrel Report for client smacker1
connect: max=23ms  min=0ms avg= 5ms from 4 clients
Query_type      num_queries     max_time        min_time        q_per_s
select_index    80000   0       0       20480.54
%super-smack ./select-key.smack 4 10000
Query Barrel Report for client smacker1
connect: max=1ms  min=0ms avg= 0ms from 4 clients
Query_type      num_queries     max_time        min_time        q_per_s
select_index    80000   0       0       19734.14
%super-smack ./select-key.smack 4 10000
Query Barrel Report for client smacker1
connect: max=1ms  min=0ms avg= 0ms from 4 clients

select_index    80000   0       0       19846.49
%super-smack ./select-key.smack 4 10000
Query Barrel Report for client smacker1
connect: max=1ms  min=0ms avg= 0ms from 4 clients
Query_type      num_queries     max_time        min_time        q_per_s
select_index    80000   0       0       20045.10
%super-smack ./select-key.smack 4 10000
Query Barrel Report for client smacker1
connect: max=0ms  min=0ms avg= 0ms from 4 clients
Query_type      num_queries     max_time        min_time        q_per_s
select_index    80000   0       0       19544.33

but it still can not beat phkmalloc. :-)
