x264 speed problem while running script-based benchmark

[Giovannie]

Hey there,

I'm totally sorry, if the thread is in the wrong part of this forum, but as I didn't find any good place to ask about problems concerning x264...

My problem is as following: I want to run a small x264-based benchmark from the german voodooalert forum (http://www.voodooalert.de/board/index.p ... 3&pageNo=1) and it works basically fine but much to slow. I have already run this benchmark several times (see http://www.xin.at/x264/?comp_id=8&searc ... allsystems) and wanted to rerun it on my old Thinkpad T23 Laptop but with a more modern version of the x264 Software to see what is the speed difference from older to modern x264 versions on old Pentium III Computers, but with a modern build of the x264 software I'm getting 1/4 of the speed I got before.

Up to now I have no Idea what might be the problem.

System:
Thinkpad T23 (see http://www.thinkwiki.org/wiki/Category:T23)
CPU:Pentium III-M 1,2Ghz
RAM:1GB
OS:Manjaro Linux (net version)
x264 version: 0.148.2579

Benchmark is using cpu capabilities MMX2, SSE and Cache32.

As said before, it ran much faster on Windows with version 0.107.1745 of the x264 software.

The computer is definitively not swapping but I get the impression it might not be using all of the cpu capacity, as its fans aren't spinning at maximum speed. I'm booting into textmode (console) so I can't use any GUI-only tools to inspect the system.

The default x264 parameters have changed.
