    Maybe what you say is my paper named "General Performance Assesement of the 
L4/Fiasco Microkernel".  In this paper I use lmbench, bonnie++ and 
AIM-suite9. But I don't use lmbench, bonnie++ and AIM-suite9 to test the 
Fiasco itself but test the the performace loss between l4linux-2.6.16 and 
linux-2.6.16.
    In this benchmark I login into l4linux
 with a console because in this way we 
could ignore the effection of graphic interface for performance loss. It is 
not complex but only a confiugration problem. If you want to login l4linux 
with console you could use the configuration file like this:
 
modpath "(hd0,2)/boot/L4Linux"
task "vmlinuz26" "earlyprintk=yes console=ttyS1,115200 init=3 mem=256M" 
root=/dev/hda3"
all_sects_writable
    
    Is this clear?
    Thanks.

I use this bootloader:
title
 Fiasco, Console, Loader, Tiny Shell (run)
root (hd0,2)
kernel /boot/fiasco_mod/bootstrap -modaddr 0x02000000
module /boot/fiasco_mod/fiasco -nowait  -serial_esc -comspeed 115200 -comport 1
module /boot/fiasco_mod/sigma0
module /boot/fiasco_mod/roottask task modname "bmodfs" attached 3 modules
module /boot/fiasco_mod/names
module /boot/fiasco_mod/log
module /boot/fiasco_mod/dm_phys
module /boot/fiasco_mod/l4io
module /boot/fiasco_mod/con -vbemode 0x117
module /boot/fiasco_mod/simple_ts -t 300
module /boot/fiasco_mod/bmodfs
module /boot/fiasco_mod/run
module /boot/fiasco_mod/libloader.s.so
module /boot/fiasco_mod/libld-l4.s..so
module /boot/fiasco_mod/loader --fprov=BMODFS run

I have to compare l4 with ecos. I want to use lmbench, bonnie++ and AIM-suite9, my questions are:
- How can I use those benchmarks when I boot Fiasco?
- Where can I put those benchmarks for use them when I
 boot Fiasco?
