That said. There are some advantages when using SimpleWorker such as the web interface, scheduling recurring jobs, and other useful options. Especially when you aren't running on Heroku, and memory is an issue if you have a small VPS. In that case, offloading background jobs to SimpleWorker is ideal. But I find that HireFire will make Heroku Workers cheaper than SimpleWorker due to the fact that jobs appear to take (a lot) longer to finish on SimpleWorker than on Heroku (probably due to the start up time? I'm not sure why).
I find Heroku + DJ + HireFire so much simpler, either using that handle_asynchronous method, or just called delay.my_method(*args) is brilliant. No need to think about isolated code or credentials due to the environment variables that are already set on Heroku.
I should look in to integrating Navvy and Resque as well.
The isolated code issue has been a big issue, and we're addressing this through calls like merge_gem(), and soon merge_mailer(). It's a challenging task, and we see the gaps, but we're improving every day.
Runtime: this is also a top priority. We're working with each and every customer to ensure that their workers execute quickly. 3 seconds vs 30-60 is totally unacceptable and we won't leave you hanging here.
Queue speed: we're prototyping alternatives to http queuing which will dramatically speed up queue times.
This is just the tip of the iceberg for roadmap... Great work on HireFire. I see cases for both. Potentially massive parallelization on SimpleWorker (hundreds if not thousands of concurrent jobs), advanced scheduling needs, etc.
Anyways - we're listening - so any and all feedback is well received. If anybody has needs outside HireFire, in conjunction with, or otherwise, shoot me a line and we'll get you up and running at no cost to start.

I think for me the hardest part was getting it to work the first time, waiting quite a while for the jobs to run to see if I managed to get it to work. The merge_gem is a huge improvement, though, handling credentials and re-connecting databases and other things are quite a hassle to set up (imo). I have to say that once it's all set up, and if the 30-60 start-up issue is gone, that it does seems like a beast for processing a lot of jobs concurrently and is exciting.
I'm definitely still looking forward to seeing future progress of SimpleWorker. So please do keep up the good work!
