So what are the scalability challenges of
a large social network?
Well the c10k problem
really pointed at the
kernel TCP/IP stack, SIRQ section, and
Workqueues, as the root of all evils.

Now with HLS binaries (video) being
mandatory (ehem TikTok), it all comes down
to bypassing much of the kernel code.
Here at Ye.pe, technologies like Vivoj.com
are being extensively tested.
