Beginning about three weeks ago, there has been a dramatic slowness in opening/loading all pages - including the log-in page, watchlist page, all articles, etc. What used to take only 5 - 10 seconds (tops), now takes up to five minutes (seriously!). The log-on page literally takes 3-5 minutes to load and appear. When I fill- in my ID and pw on the log-in page, it literally takes 3-5 minutes to confirm the log-in and get me to my watchlist. Trying to open any article takes 3-5 minutes per page. Clicking on the "Edit" tab takes 3-5 minutes to open an edit page. Clicking "Preview" takes 3-5 minutes to open the previewed text, etc. Clicking "Save" after making an edit takes 3-5 minutes. Clicking History takes 3-5 minutes, checking the "diff" tab takes 3-5 minutes - you get the idea. I'm behind a corporate firewall, but they don't report any change that could have caused this within the past month. This problem does not occur when I access from my home computer. Do you know of any problem that's causing WP to not play nice with corporate firewalls?
I'm experiencing some of this too within the past week or so. Gmaxwell used me and a couple of others as guinea pigs in #wikimedia-tech last night, and sent the results off to mark. His guess was some network congestion on the route that certain clients were using. I'm sure he wouldn't mind me reposting some snippets here, for what they're worth to those of us who are suffering. <NullC> adri: From Simetrical's packet traces it's clear the delay is due to high packet loss between him and tampa. <NullC> Lots of retransmits. <NullC> adri: I had him pull once from AMS and ones from tampa.. The AMS is fast the tampa moves like a slug in mud. <NullC> adri: I'm guessing whatever upstream is involved has a saturated peering link to someone... or the like.. The trace routes they are doing for me now will tell me more. <NullC> Hildanknight: I'm not sure yet. My best hyphothesis right now is that there is a congested connection inside one of Wikimedia Tampa's ISPs. Becuase of this congested link, some people would see slowness while others would not depending on where they are on the internet. <NullC> This many not, however, be correct. <NullC> I wouldn't bet money on this being the correct solution until I have identifyed the link which is congested. Because traffic is most likely taking a different path from Simetrical to Tampa wikimedia than from Tampa wikimedia to Simetrical, it's a little hard to research. He gave this as a workaround: <NullC> Hildanknight: You will be much faster for now as a workaround if you adjust your browser settings and set your proxy to 145.97.39.155 port 80, but you will only be able to go to wikimedia sites while it is set that way.
Well, I did the 145.97.39.155 port 80, and three minutes to open. I'm going to see if I can get the MIS tech folks here to ping the Main Page, and see if that turns up anything.
Network slowness somewhere on user side. Reopen this bug with a traceroute if the problem is still around.
