I noted that the server status page takes some time to show (around 5 seconds, sometimes even 15 seconds). Is it generated every time it is requested? Or is it cached? |

Also there is general overload of the CERN services, network, file system, nodes probably due to all that LHC data :-) Eric. |

But the MB and the homepage are fast. Only the server status page is so slow :S |

True; maybe I can persuade my IT support to have a look at Memory/Disk usage (the server CPU usage is near 0). Eric. |

The status page has a delay in most projects, some are even so slow that you get a browser timeout now and then and - even though it should be cached - it goes down when the database is down. The first step I would take would be to separate the actual Server status and the Computing status or switch off this or that information block and see how the behaviour changes. Some projects have parts of the server status page integrated into their start page, so I guess those are the parts that work without delay. A lazy option (but still a good one) would be to set up a cron driven wget job that downloads the dynamic server status page into a static snapshot and link that snapshot to the start page. For the cron job, 15 minutes should be fine. |
