RE: is mpm_event safe for modperl handler? [EXT]
People use nginx - probably because they haven't come across mpm_event. The two are I think comparable speed wise, but out of the box mpm_event is more flexible - and the nice thing is that you can develop a site on a single mpm_worker instance and easily migrate over to the mpm_event/mpm_worker module. It is nice to use the same configuration language on both sites... mpm_event like all Apache mpm_s is much better at handling "issues" where nginx just goes F* and returns nothing.

I think running Ignix as front-end server and mod_perl for backend server is the more popular choice. If you want the speed of mod_event for static content and the power of mod_perl for dynamic content - the best way is to run a lightweight mod_event apache in front of a mod_prefork to run the mod_perl
RE: is mpm_event safe for modperl handler? [EXT]
If you want the speed of mod_event for static content and the power of mod_perl for dynamic content - the best way is to run a lightweight mod_event apache in front of a mod_prefork to run the mod_perl tbh this is exactly the set up most people use for other heavy backends (mod_fastcgi etc) but you still benefit from the power of mod_perl for your perl I do this anyway as the mod_event bounces really quickly in comparison to the heavier mod_worker client (especially if you pre-cache a lot of your perl) so can handle "maintenance" events much better... Also all the stuff like SSL etc is handled on the mod_event instance keeping the mod_worker instance clean.. It also allows you to run two apaches on a single box - a "test" and a "live" -Original Message- From: pengyh Sent: 05 August 2022 02:21 To: modperl@perl.apache.org Subject: Re: is mpm_event safe for modperl handler?
