Beta Branch add NGINX_IOURING_PATCH variable support in 123.09beta01

I am seeing the same.

Code:

2019/09/02 13:50:06 [crit] 20515#20515: *59091 aio read "/home/nginx/domains/bamapolitics.com/public/wp-content/uploads/2019/01/Prichard-AL-150x150.jpg" failed (14: Bad address) while sending response to client, client: 68.35.162.46, server: www.bamapolitics.com, request: "GET /wp-content/uploads/2019/01/Prichard-AL-150x150.jpg HTTP/1.1", host: "www.bamapolitics.com", referrer: "https://www.bamapolitics.com/alabama/counties/mobile-county/"

Hi,


I'm following the guide on boosting LEMP stack here and trying to both 2 tips "Leverage Nginx Thread Pooling" and "Leverage Linux kernel 5.1+ and Nginx io_uring patch for better Async I/O". So I have two aio directive definitions in Nginx configuration file:

Code:

aio threads
aio on

Now I cannot start Nginx. If I run Nginx -t, it prompts me the start failed because I have duplicate aio directives declared. I have also checked the Nginx document about the directive, but not sure what value I need to use if I want to have both options. I guess if I use just "aio threads", it also means aio turned on, but not sure.

And btw, should I use thread pool feature if my VPS just has 1 core CPU and 1024 MB memory? If I can, what is the pool size should I consider configuring?

Thanks!

 

Updated to latest kernel 5.7+

using NGINX_IOURING_PATCH='y' in variable

do not see anything in nginx compilation log nor nginx -V showing --with-file-aio

On KVM VPS

 

try

Code (Text):

NGINX_IOURING_PATCH_BETA='y'

 

Ok Will try that, thank you for update

 

Using ELRepo 5.4.x Kernel, I got this:

 

Not present, even the --with-file-aio on Nginx -V isn't present, weird.

 

Oh I use a slightly different config:
NGINX_IOURING_PATCH='y'

 

My benchmark here:

Conclusion, it seems a downgrade to performance.
Unless you serve pure static files.
