[Astlinux-devel] curl vs. wget

Hi Devs,

FYI, with the advent of the "Let's Encrypt" project https://letsencrypt.org , the team thought it is worth adding some missing HTTPS support.

In particular we use the Busybox 'wget' for various downloads which does not support HTTPS, so we need to switch to 'curl' for those downloads.

It made me wonder how such a change would effect our current lowest-end supported board, the net5501/alix.

I just finished some testing worth sharing, downloading the same AstLinux run image...

(Maximum percentage CPU using 1 of 1 core)
net5501 curl HTTPS 26 %
net5501 curl HTTP  7 %
net5501 Busybox wget HTTP 3.5 %

Approximate same  650 KB/sec (downloaded to /dev/null) for each.

Jetway NF9HG-2930 curl HTTPS 28 %
Jetway NF9HG-2930 curl HTTP  12 %
Jetway NF9HG-2930 Busybox wget HTTP 8 %

Approximate same 4050 KB/sec (downloaded to /dev/null) for each.

Good to know that the net5501 can still handle HTTPS with no increase in download time.
