Have you seen surveys? Do you know WHY nginx is growing so fast? Do you even
know WHAT the nginx is? It's caching web-server. It can serve static web-
pages and protect "real" server (often Apache server) from slowloris
And it DOES NOT use "a heavy-weight polling syscall" - all moder operating
systems offer alternative...
P.S. The real motivation was not to fight slowloris attack - it was to
reduce server load when it talks with thousands of dial-up clients. Think
about it: if you have huge number of very slow clients the dynamic
is the same! Server processes or threads are tied for minutes when they
serve "feature-rich" pages to clients who only consume 1Kb per second.
Apache was unable to work with it (nginx author tried to fix it for years)
so new web-server was born. And as statistic shows real admins who are in
charge of real sites know all about this problem. Tempest in a
