[Samba] Non Samba question

Fri Aug 23 11:33:50 UTC 2019

Well yeah, offcourse.. 

Its a "common" windows problem that windows is slowing after updates, 
because they harvest more info and for that they use internet. 

If you able to test a bit, i suggest, setup a squid proxy, with ssl bumping. 
You can ask me the needed settings, or look them up in the samba list, 
since is accedently so now and then mail samba inplace of squid list. ... Like today.  :-/ 

Try this: 
Remove the gateway adres from you ip, and enforce the proxy. 
Now check what is going to the internet. 

What i noticed for example after last update, while tailing my squid logs, it that, 
All the "live" things want to go to the internet. 
And i dont like that so i disabled that straight away and hee, my pc responded quicker. 

;-) 

Just keep in mind, that if you resolving is good, these things "should" be hardly to notice. 
But i notice a lot, if i just "site/work" with a pc, i already notice if things are off. 
But thats due to 30 years of working with windows..  ;-) 

After every (big) windows update i also review all windows settings you see in "Setting" (not control panel) 
Especialy : system, privacy, personal settings, Apps Accounts, Gaming, Search. 

Disable that "nice to know,tips,tricks, everywhere you find them. 
Results in about 3-5% speed gain. ( and in CPU terms 3-5% is a lot of $$ when you buy new ) 

Then you might want to ask why i use windows then and not Linux desktop. 
My games still dont run on Linux Desktop. :-(  
And the company, its users and customers are just not Linux ready
I tried it, linux desktops, but not successfull yet. ( this was about 4-5 years ago )
Maybe i'll try again next year, things are going fast in development.. 
Who knows. 

Have a great weekend. 

Greetz, 

Louis
