    Hi all: I've been asked to put together hardware specifications for an Elgg site with approximately 20,000 registered members. Has anyone done any research on this? What does the community.elgg.org site run on?  
    • yr ques seems too generic ;-) "performance' per se is not for a one sentence answer. there's many tools around to monitor apache and mysql performance, e.g. here's a live sample -->

    • Oh sorry about that.  I'm not quite an expert on this. :S

      Ok, so you said that you have 120 to 140 concurrent users.  How much load does it give to your server?  The CPU usage to be specific.  Does it reach 50% or do you still have lots of headroom just in case your concurrent users might spike up?

    • you might wanna check out a little on how performance is monitored and analyzed, etc.. ;-) cpu usage ? how many cores do you have ? speed, etc, etc ? sample -->
      Tasks: 149 total,  11 running, 138 sleeping,   0 stopped,   0 zombie
      Cpu(s): 66.2%us, 14.3%sy,  0.0%ni, 19.3%id,  0.0%wa,  0.0%hi,  0.2%si,  0.0%st
      ps: our cpu's are under-loaded;-O, ram under-loaded...!

    I'll answer myself: because I had ordered the tools incorrectly in the tools administrator. The editor needed to be at the very bottom, in my case.  
  • mk added a new discussion topic List of all site members in the group General Discussion
    I would like to show a list of all site members, along with some of their profile information (like location, etc.). All logged-in members would be able to view the list. Ideally, the list could be sorted/filtered by the profile data. What is the...
