Our Tuesday outage ran a little long this week because we're no longer dumping to the super fast Snap Appliance as we converted that space into more workunit storage. Instead we're currently writing to the internal disk space on thumper, which is vast but much slower for some reason. This situation will evolve, so nothing really to worry about. We also made the database change to fix the cryptic bug noted in this thread. Pretty much just adding a new row to the middle of the application table so it was in sync with the data structs in the code. And yep, after that it was behaving normally, even without our "force" to set values to where they should be regardless of what was erroneously culled from the database. So we're calling this fixed. I also got the new server "bane" on line as a third redundant public web server. Perhaps you noticed a speedup? Perhaps you noticed some unexpected garbage, broken links, or weird php behavior? Let me know via this thread if you see anything obviously (and suddenly) wrong with the web site. Over the coming days we will retire the current web servers kosh and penguin. Bane is a system with two Intel quad-core 2.66GHz CPUs and 4GB RAM in 1U of rack space. Alone it is more powerful than kosh and penguin combined, which together account for about 6U of rack space. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

Retrieval of the "my computers" page is quite sluggish (but it does work) It's not too many computers, it's a lack of circuit breakers for this room. But we can fix it :) |

With the "pebble" in the thread title, I don't want you to think that I'm "stoning you", but have you passed on the information about the deadline situation that Richard Haselgrove and I brought up a week or so ago? I would think that if you reduce the amount of time given (the deadline) for tasks down to something less than what they are today, yet still generous, you would keep slow / less-allocated hosts from building up as large of a work cache so that faster / more-allocated hosts that returned their results quicker would likely not have their returned results lingering in storage so much, thus decreasing the overall storage needs. As for the web server performance, right now is not a good time to evaluate that... I'll give a yea/nay later... |

Feedback: 1) public web server isn't just slow it is adiabatic (at the time of this post) 2) 8 Intel cores with only 4GB of RAM? You must not be running Windows! |

Feedback: Windows is too costly for a project running on fumes for funding. They're switching over to Linux on most of their servers. |

Well, it has been 6.5 hours since I posted saying I'd comment on the web server performance later, and the pages are still slow to load... [edit] 15 minutes after I tried to post the original message, it was still trying to reload the thread. I had been off looking into my 401(k) and not watching the forum. So, "slow" is not even close to being the correct term for how abysmal the forum pages are performing... [/edit] |

I dunno......I just got home from working an 11 hour shift, and at the time of this posting, the webpage response in all the forums is verrrry snappy! "Freedom is just Chaos, with better lighting." Alan Dean Foster |

It is not my connection... My connection is advertised as 1.5Mbit... (slowest of the plans available), and here's speedtests to San Jose: Los Angeles: and San Francisco: |

I dunno......I just got home from working an 11 hour shift, and at the time of this posting, the webpage response in all the forums is verrrry snappy! If I try the test from Wisconsin to San Jose, I get this..... If I try the test within Wisconsin from Menasha to Germantown, I get this..... Both a bit different from the 6016/768 DSL I am paying for...but you never know what the weakest link in the chain is. Still.....the Seti servers seem velly happy at the moment..

This has been discussed in this forum by Matt. Matt is not the person who controls the length. He has passed on the concern, but he personally can not do anything about it.

Hi Matt, I have very recently returned to Seti after a long break, and I'm not really sure of how the credit system works yet, but since the outage, when I look at my stats (although the total credit seems right) in the your results I seem to have lost most of the work units done on the 17th. And the number of results returned for each computer seems to have gone down a little? |

Welcome back! In order to keep the BOINC database nice and trim (for faster I/O) we only keep 24 hours of completed results around before purging them, which is why they disappeared from your list. The credit, science, etc. of course remains - we're just removing the excess database records. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.
