While we're at it: I just compiled lame-3.70 on my alpha. I also have a
laptop running i386.
I'm using "lame -v -b 128". (Without the "-b 128", it's even worse)
On my laptop, I get about 1:2 performance, e.g. 15 minutes to compress an
On my alpha, I get about 1:4.5 performance, e.g., 28 minutes to compress an
The laptop: PII-233, probably a "mobile" pentium II of some sort. 96MB of
The alpha: PC164-500, 256MB of memory, using all 8 SIMM slots.
The alpha otherwise runs probably 2x the speed of the laptop.
Both are using IDE disks. The alpha was compiled with -O4, various options
suggested by the Makefile, -DFLOAT=double (stolen from our patches directory
in pkgsrc for lame 3.50), and -Mcpu=21164a -Wa,-m21164a or whatever that was
to tell it it's on a 21164a.
The laptop is 1.4ZD, the alpha is 1.4ZD.
This can't be right. :)
