It is strange, really strange. I have seen that slowness three times within a few minutes on my watchlist, but now I do not see it anymore? Did the servers take a break for a cup of tea?

@ema It was not a single timeout. A chunk of data (the start of the page) was rendered by the browser very fast, but it stuck. And from that moment the browser added line by line, sometimes character by character, sometimes larger chunks arrived. When I scrolled down to the end of the page, I could read the data faster than it arrived. As I said in the IRC channel: Slow like a acoustic coupler.

Krinkle, I refresh my watchlist maybe 100 times a day. It is usually fast, I cannot see the rebuild *blink* refreshed. But it started a few weeks ago

Jun 07 00:24:57 <Wurgl> Really strange: Very often when I open a wiki-page it opens within a blink of an eye. But sometimes I can watch the bytes while they arrive. Slow like a acoustic coupler … (I have a 150 Mbit connection)

A really bad quality video of refreshing my watchlist. You see the watchlist and at 0:17 - 0:36 you see a slow refresh.

Okay @Lea_WMDE, I thought/hoped it was deployed already on last Thursday. I tried on Beta and cannot reproduce any problems. So eagerly waiting for Thursday … If you like you can close it, I will not reopen any more.

Wurgl added a comment to T223971: Old cloudvirt (with Intel Xeon) are half the speed of newer ones (Intel Sky Lake).

Could this difference be caused by prevention of those design flaws called Spectre & Meltdown?

the last days:
2019-06-05 connected to labsdb1010, 1 large query "SELECT DISTINCT pl_title FROM pagelinks LEFT JOIN page ON page_title = pl_title AND page_namespace = pl_namespace WHERE pl_from_namespace = 0 AND pl_namespace = 0 AND page_id IS NULL" took ~55 Minutes which is okay.

Maybe important: The URL gets truncated to https://en.wikipedia.org/w/index.php once you select "Remember selection for future searches" which is accessible when you expand/open "Search in:". Actually not for the current search, but for all following. And this field is accessible only when you are logged in. See T224796

Some background: There are a lot of "redlinks" in articles. Like [[Ac Aceca]] where an article [[AC Aceca]] exists, this is an example of uppercase/lowercase difference, the same is true for letters with accents and similar additions, like a redlink [[Diana Castano Sarrias]] with an existing [[Diana Castaño Sarrias]].
