The queuing means you can do with more web workers
Additionally your median times look pretty high, can you get this on a faster CPU?

Unfortunately, even if the reason for the slowness is this plugin, I must say that this plugin is one of the main plugins of our community and can not be removed from us in any way, and users become heavily depended on it! 
We currently use 24 web workers. Our Discourse is installed on a VM with 24 CPU cores with 2 GHz processing power and 24 GB of RAM. Unfortunately, it is not possible to change the main server now, unless we have no other way to improve performance.
Do you think that in the current situation, increasing the number of web workers can help to improve performance?
More web workers may reduce the queueing
You are trying to eliminate the orange lines from the active web request graph
Performance though will not get any better for your typical median request

Thanks, I understand now. So by looking at the graphs we can see if the number of web workers is enough or not enough for the system.
But according to you, to improve the speed and performance, we now need higher processing power and changing the parameters will not help more.
Be sure to test this at the earliest opportunity and inform the result.

¿Cuál es el origen de los 502? ¿No hay suficientes unicorn workers? Acabamos de mudarnos de servidor y los usuarios han estado informando de 502 ocasionales después de la mudanza. Tenemos un servidor de 6C/16GB y hemos configurado unicorn_workers a 16 (antes de mudarnos de servidor estaba en 12), db_shared_buffer a 4GB, db_work_mem a 60MB.
¿Podría causar 502 tener demasiados unicorn workers? (especulando ya que teníamos 4 menos antes de la migración del servidor)
Estoy tratando de ver si es la configuración la que necesitamos ajustar o algo más que necesitemos abordar.
Gracias.
Sí, eso parece mucho. Establece tus unicorn_workers entre 1 y 2 por núcleo. Para 6 núcleos, no debería ser más de 12. Dado tu búfer compartido bastante grande y mi instinto, lo establecería en 10 o así con tales especificaciones de servidor.
