Re: [PATCH 1/2] lib: add fast lzo decompressor

[Andreas Robinson]

Hi,

after enabling checksumming (adler32) and adding an overrun check, based
on your suggestions and objections, the performance advantage of LZO on
the Eee 901 dropped to 67 ms with the fast, and 54 ms with the safe
decompressor. Apparently almost half of the speed boost came from
skipping the checksumming.

At this point I don't think this idea is worth pursuing further, when
LZO is so close to gzip in performance after all.

But I want thank you for discussing this topic and taking my patch
submission seriously.

I hope I did not waste too much of your time and that I will be able to
contribute something more useful next time.

Thanks,
Andreas
