  • jacekbecela jacekbecela If this is a background process then you're fine - it probably doesn't matter too much. If you're inside a web server - try http://nodejs.org/docs/v0.3.7/api/child_processes.html (this approach also nicely scales across multiple cpu cores). 'Action rendering time' > 'The x seconds of continuous processing without letting go of the CPU'. Less than 100ms is good. Some people say: 'well, it depends' ;) 3 years ago

  • voytek9 voytek9 You write on slide 49, 'Callbacks have to return fast -- no CPU heavy stuff.' I want to move from a blocking web spider that also does some keyword matching against the returned page, to using non-blocking node stuff. Can you please give me a vague scale of an acceptable range for returning fast? I envision using node to pull a page from a remote server, then perform the keyword processing on it (less than 1s of processing for sure). Is that too CPU heavy / too long of an execution time? 3 years ago
