Slow IPV6 1st. time connections to google.com - mainly in
SeaMonkey (akin to FF 52).
(In addition to 1st time connections, there must be some "timeout", "reset" period, when this will also occur.)
IPV6
Win7 & XP (& kind of Win10)
Comcast in two separate locations, residential & business (Maryland)
Arris (192.168.100.1) TM822G modem (on the residential end, & no router)
(I have reset the modem, pin in the hole trick)
SLOW, ~20000 ms slow
No issues with IPV4
New Profiles
Set google.com to be your search engine, if need be
Open SeaMonkey
F12 to open the browser "Tools", click the 'Network' tab
Type a non-URL into the Location bar, so, 'google' will work
Observe
Disable IPV6 (I did through, Control Panel, Networking, LAN, uncheck IPV6, then ipconfig /flushdsn)
Repeat above
This is a recent situation.
Same setups, same browsers, no issues in the past.
I have not noticed (& not that I was looking) any other issues at any other sites.
Note that google is https: (obviously, & in case that matters).
mozillazine thread:
Google Search SLOW.
Last (Win7) updates were installed 6/18/2018.
Might this issue have coincided with them?
KB3185319, security update for IE11 (don't even ask how I got suckered into installing that!)
KB890830, MS's malware tool (for June)
KB4284826, 2018-06 Security Monthly Quality Rollup for Windows 7 x64-based Systems
SeaMonkey build date is 06-11-2018 (just now pulled a build of 06-26-2018 with no change).
Ideas?
