I have a v4.0.0 beta for sealed.pm that I expect will be fully operational
with mod_perl+ithreads now, but I will let it soak for a week to see what
happens in prod.

That came across as rude, Joe. Not all of us are experts at Perl internals or
track the latest changes to Perl's ithread support and/or glibc, and it's
generally been accepted in the mod_perl
LOL IF YOU THINK THE WAIT FOR ITHREAD SUPPORT WAS A LONG TIME COMING.

All of those performance optimizations are lost when you bury them behind a
mod_proxy gateway to your application server running prefork.
Moreover, your scaling model for your application server is

The entire collective engineering effort for mod_perl and mod_apreq was to
ensure our code was thread-safe, both from an httpd context and a Perl one.
We achieved that twenty years ago, but have been stuck dealing with the
fact that ithread engineering within Perl5 itself had a ways to go.

Why are you still paying attention to mod_perl development, if you don't
even care to use it to full effect?
Running a 2-tiered webserver architecture is anathema to mod_perl. It's
not distinguishable from any other fastcgi thingy out there.

If HTTP/2 becomes necessary, my lazy first answer is to enable it in my

There isn't anything else on the market that will ever touch mod_perl +
mpm_event in terms of HTTP/2 performance.
And you don't need to ever spin up more ithreads than you have vCPU cores.

Segfaults in glibc malloc should be reported to glibc developers. Not
here. There’s nothing we can do about it other than to suggest Solaris for
high performance modperl shops.

My pleasure. Nobody’s going to fix this from the modperl developer side.
We don’t care any more. That ship sailed 20 years ago. I don’t think it’s
ever not worked on Solaris, so you get what you pay for in the end.

Whatever you do, do not use Perl's sbrk-based malloc implementation. It's a
disaster with ithreads.
