fun around MIPS: qemu-system-mips

Yesterday I was surprised when discovered that,... ehm, well... I'm such a newbie in this... that most routers using MIPS not ARM CPU as I thought before
Since that, I've also tried to look at MIPS in QEMU. There is even less information about this, though debian to help I was surprised I've missed it last time when doing experiments with qemu-system-arm, but now it's very helpful with qemu-system-mips.
I used aurel32's page as a start point:
It went really good, I booted into lenny with no problems, then I've updated packages in that disk image and my next stop was this:
As you can see, debian provides ready-to-use kernel images for most systems, even versatile ARM I didn't see it when experimenting with qemu-system-arm.

So, my first uname -a looked like:
Linux debian-mips 2.6.26-1-4kc-malta #1 Sat Jan 10 21:18:48 UTC 2009 mips GNU/Linux
And now it looks this way:
Linux debian-mips 2.6.36-rc6-4kc-malta #1 Wed Oct 6 07:41:36 UTC 2010 mips GNU/Linux
Not most recent, though prettier than one from 2009

As usual, I set up gcc and built nginx. Comparing with ARM in qemu (256M) the results for building nginx 0.8.53 with the following configure line:
--conf-path=/etc/nginx/nginx.conf --error-log-path=/usr/local/nginx/logs/error.log --pid-path=/var/run/ --lock-path=/var/lock/nginx.lock --http-log-path=/usr/local/nginx/logs/access.log --http-client-body-temp-path=/var/lib/nginx/body --with-http_ssl_module --http-proxy-temp-path=/var/lib/nginx/proxy --with-http_stub_status_module --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --without-http_ssi_module --without-http_browser_module --with-file-aio --without-http_scgi_module

real	24m6.628s
user	23m22.032s
sys	0m43.867s
for mips 2.6.36-rc6, gcc 4.3.2, debian
real	14m13.772s
user	12m5.420s
sys	2m5.530s
for arm,, gcc 4.4.3, gentoo

I don't really know what I'm doing... I mean why, I guess I'm just a bit crazy so always looking for something new to me in order to try that and share some successful results
Guess I'll append real P1-200 mhz results for building nginx here a bit later
