Please make chef-client more light weight.
Currently this is a show stopper for me. Chef-client puts too much load on my servers and uses too much memory. So what I am doing for now is only running the service manually and then shutting it down when not in use. Obviously this is less than ideal as you scale up and kind of defeats the purpose of chef in the first place.
Most often in our observation, the chef-client is ~30Mb resident when idle and usually uses ~120Mb when running recipes of significant complexity. You can use the chef-client cookbook to set up the chef-client to run out of cron, which may help in this situation. Also, if you’re using search, that can cause high memory usage, and we do have plans to make that more efficient this year.
Thank you, -joshua
