使用sidekiq、redis发送电子邮件

我有一个关于ruby中sidekiq的问题。 我正在建立一个发送活动电子邮件的系统,每个活动发送1万到5万封电子邮件。

receivers.each do |receiver|
    begin
      email_sending_log = EmailSendingLog.create(email: 
        receiver["email"], sender: sender["email"], content: 
        content["value"], status: "REQUESTED")
        EmailWorker.perform_async(adapter, receiver, sender, content, subject, email_sending_log.id.to_s)
    rescue Exception => e
    end
end

你们有什么想法来加速我的系统吗? 或者举个例子来加速sidekiq,redis?
