OptiPNG ARM for Zyxel (ARM926EJ-S)

OptiPNG for optimizing PNG files directly on Your Zyxel NAS!

NEW: Now in installation package! Installs with funpkg command!

Now you can optimize Your PNG files directly on Your Zyxel NSA-210 or 220 Plus (other file
server basing on ARM CPU should be supported). This version is especially optimised for ARM926EJ-S that Zyxel NSA-220 Plus contains. This time I didn't test speed difference with previous non-optimised version but it should be 10% faster as LAME was ;)

Here is some data generated by compiled program. As you can see it's working perfectly:

Lame MP3 ARM for Zyxel (ARM926EJ-S)

Lame less lame on ARM?

Yes, it is! There in a new compilation of Lame I did a long time ago for Zyxel NAS. This one is especially optimised for ARM cpu that is inside this NAS file server. It's still painful slow but it also is 10% faster than previous version. Here are short results of compressing 600 frames:

lame.2 is version is optimised especially for ARM located in Zyxel NAS.
lame.1 is version compilled with default settings.
