why metasploit is so slow?

[junkoi2004 at gmail.com (Jun Koi)]

hi,

i am new to metasploit, and wondering why it is so slow? for example,
"./msfcli -h" takes a minute or so on AMD Turion64, with 2GB RAM. and
that command does nothing, but only shows some messages.

other commands are equally slow.

i am sure it is possible to fix this kind of thing, if we want to
optimize for performance.

i am using Linux.

Thanks,
J
