    Server Slowdown

    I'm aware the server has been up and down more than a politicians rent boy (allegedly ).

    I've just found the problem........YAHOO SLURP.....the Yahoo search engine spider, throwing in 100's of searches a second. As Yahoo supplies less than 1% of traffic, that's a bit of liberty, so I've set it up so they can only scan 1 per second from now on.

    On top of that, the server is having another GB of memory added in the next 24hrs.

    Did you get more hits due to the AVG issue? Or are we all to clever not to use that application?

    My current subscription to Eset NOD32 AV expires next month, and I'm looking around for a decent free AV as a replacement. Having seen the link scanner nonsense that AVG supplies, I can discount that piece of rubbish straightaway. I don't like AVG anyway as it takes up so much CPU. NOD32 uses very little system resources, updates itself 6 times a day and can be fully configured.

    You couldn't make it up with Yahoo.

    I allowed it back on all the sites bar the one it was basically doing a "Denial of Service Attack" on, and banned it in the Robots.txt

    It completely ignored that, and brought the server down again last night

    YAHOO

    So I've banned it now via its IP on the article site. I know what it's done. I added software to list sitemaps for Google last week for better indexing, and Yahoo managed to find them and seems to want to index all 107,000 articles at once!!!

    Oooo ... I remember those old days! A Teletype 43 and an acoustic coupler. I ran up a £500 phone bill in the first quarter ... and the neighbour with whom I shared a party line complained that she could never use her phone!

    i'm sad to say that i had some thing similar if not the same , it was made by Texas instruments and in those days there was only a few bbs, and all input/output was sent to the built in thermal printer, it was the size of a medium suitcase and was pretty heavy to move around

    The Yahoo Slurp should not load the server anymore than Google and other spiders. Yahoo appears more in the online users page because it hits from a range of IP addresses and vb considers each IP a different "guest" whereas each new Google index comes from the same IP address so vb considers it as one IP.

    This Yahoo was one IP, and was bringing down the article directory trying to read over 100,000 pages as quick as it could load them, nothing to do with vB.

    I left it banned for a few days, and the server ran at an average of 0.5, I let it in again then to test it and it brought the server to a crashing halt again, with an average of 86!!!

    You can slow down the rate that Yahoo hits the server via the robots.txt file - I am sure that you know that though (Assuming you use a proper HTTP Server that is!)

    I know that but it ignores it.

    It's my server, all 100% of it, and Yahoo is no loss on that site with only around 200 hits a month from Yahoo, and 10,000's from Google.
