ruby rails sidekiq performance Ruby

I'm getting frustrated with Does anyone know how to I'm building a feature where I'm working on a personal project and I'm experiencing significant response time issues in my Rails 7.1 API, particularly when endpoints trigger background jobs using Sidekiq... For instance, a request to create a user and send a welcome email is taking longer than expected, often exceeding 2 seconds. Here’s a simplified version of my code: ```ruby class UsersController < ApplicationController def create @user = User.new(user_params) if @user.save WelcomeEmailJob.perform_later(@user.id) render json: @user, status: :created else render json: { errors: @user.errors }, status: :unprocessable_entity end end private def user_params params.require(:user).permit(:email, :password) end end ``` While I expect the job to enqueue quickly and the response to return immediately, the actual response time seems adversely affected when the job is queued. I’ve verified that Sidekiq is running and processing jobs in the background, but I still see delays. I’ve attempted to isolate the issue by checking the performance of the `WelcomeEmailJob`, which looks like this: ```ruby class WelcomeEmailJob < ApplicationJob queue_as :default def perform(user_id) user = User.find(user_id) UserMailer.welcome_email(user).deliver_now end end ``` The `deliver_now` method seems to be the bottleneck, but I’m not sure how to handle this while still ensuring that the email is sent. I've also experimented with using `deliver_later` instead, but that doesn't seem to alleviate the initial delay when the job is queued. Additionally, I checked the Sidekiq dashboard and noticed that the job queue is generally empty, which rules out a backlog as the source of the delay. I would appreciate any advice or best practices that could help improve the response time while still using background processing for sending emails. I'm working on a API that needs to handle this. I'd be grateful for any help. Is there a better approach? I'd really appreciate any guidance on this. I'm developing on Ubuntu 22.04 with Ruby.
