我过去常常把很多代码封装在Thread.new {}中，然后开始偶然发现Sidekiq，使后台任务变得更容易一些。几周后，这很令人失望，我不知道这是我把代码输入sidekiq工作人员的方式，还是交易是什么。
例如，
[1] pry(#<DomainWorker>)> domain = Domain.find_by(unique_id: @unique_id)
[2] pry(#<DomainWorker>)> urls
=> [{:url=>"http://admin.example.com/"}, {:url=>"http://example.com/"}, {:url=>"http://www.example.com/"}, {:url=>"https://admin.example.com/"}, {:url=>"https://example.com/"}, {:url=>"https://www.example.com/"}]
[3] pry(#<DomainWorker>)> domain.domain_urls.build(urls)
=> [#<DomainUrl:0x0000557c97f2a3c8 id: nil, domain_id: 32, url: "http://admin.example.com/", created_at: nil, updated_at: nil>,
#<DomainUrl:0x0000557c97cc6e38 id: nil, domain_id: 32, url: "http://example.com/", created_at: nil, updated_at: nil>,
#<DomainUrl:0x0000557c97cadd70 id: nil, domain_id: 32, url: "http://www.example.com/", created_at: nil, updated_at: nil>,
#<DomainUrl:0x0000557c97c9c8e0 id: nil, domain_id: 32, url: "https://admin.example.com/", created_at: nil, updated_at: nil>,
#<DomainUrl:0x0000557c97c7ed18 id: nil, domain_id: 32, url: "https://example.com/", created_at: nil, updated_at: nil>,
#<DomainUrl:0x0000557c97c43df8 id: nil, domain_id: 32, url: "https://www.example.com/", created_at: nil, updated_at: nil>]
仅运行domain.domain_urls.build(urls)命令就需要大约15秒的执行时间。如果我打开rails c，这个命令会立即运行。
这是否违反了从sidekiq工作者或其他人那里操作模型的最佳实践？不知道为什么有时需要15-20秒，下次需要5秒，等等。这非常不一致。我甚至有一个MailWorker，有时发送电子邮件需要2秒，或者2分钟。不确定交易是什么。
这是我的config/sidekiq.yml配置文件：
development:
:concurrency: 50
production:
:concurrency: 50
:queues:
- default
是我的代码，还是Sidekiq不擅长做这些任务？我在这里错过了什么？
编辑
在我的开发环境中简单地禁用eager_load似乎会使取得一些的进展。
在config/environments/development.rb:中
更改
config.eager_load = false
至
config.eager_load = true
它工作了一段时间，但在一堆任务排队并完成后，它又开始挂起。现在它又卡住了。
如果我在MySQL中运行show processlist，我会看到以下内容：
mysql> show full processlist;
+----+------------+-----------+-------------------+---------+------+----------+-----------------------+
| Id | User | Host | db | Command | Time | State | Info |
+----+------------+-----------+-------------------+---------+------+----------+-----------------------+

| 50 | root | localhost | NULL | Query | 0 | starting | show full processlist |
| 55 | app_dev | localhost | app_portal_dev | Sleep | 1059 | | NULL |
| 57 | app_dev | localhost | app_portal_dev | Sleep | 1028 | | NULL |

| 63 | app_dev | localhost | app_portal_dev | Sleep | 191 | | NULL |
+----+------------+-----------+-------------------+---------+------+----------+-----------------------+
8 rows in set (0.00 sec)
此外，如果我向Sidekiq工作者发送终止TTIN信号，这就是输出：

Rails开发模式的自动加载是单线程的。您可以将Sidekiq设置为任何您想要的并发性，但您仍然有一个巨大的互斥体来单线程处理您的作业，这样它们就可以安全地自动加载。打开eager_load或切换到生产模式将禁用自动加载。
并发：50太高了。不要将其设置为高于25。
也有可能您有大量的线程，但数据库连接量不同，请在config/database.yml中设置pool: 25
TTIN输出或数据库似乎没有任何问题。Sidekiq非常适合使用Rails和ActiveRecord。我们运行一个高负载的生产环境，有大约3万个并发线程(分布在几十个工作服务器上(，Sidekiq的表现非常出色。不要在开发模式中设置不必要的高并发性，尽管如果您只处理一个并不重要的任务。
尝试在本地调试Sidekiq工作程序-在方法的开头设置断点，并找到它变慢的地方。Sidekiq本身不太可能达到
