Forum .LRN Q&A: Re: Appreciate help with dotLRN performance
Thanks for the pointer, Jeff. I reported the server's response to ps almost 10 minutes after my last interaction with dotLRN. The same processes linger on even now, five hours after I last posted the previous message. Could this indicate un-exiting processes?
I will go ahead and test dotLRN out with apache. I do not, however, seem to understand the distinction between OpenACS and dotLRN. My bad!
You also don't seem to understand the difference between a thread and a process. AOLServer is multithreaded, it creates threads within the server process to handle requests and typically those threads do not go away until the server process exits. ps on linux has the annoying -- not sure if you would call it a feature or a bug -- that it displays threads like they are processes, these don't really take any extra memory than is already taken by the server (note how they are all listed as being the same size and were all created at the same time -- thats because its all just the same server process).
