Docker Xampp crazy memory usage - docker

I'm using docker xampp to host a wordpress site.
It's on the Ubuntu Server 22.04.
I found that if I open each session or let's say each tab in browser connected to the website, the memory usage on the server increase 3x~5x MB. (watched by free -h).
That's a crazy memory usage. On windows with xampp native 1 session only cost 2~5MB on server.
What's going wrong? shoud I use apache + mysql + php by independent, instead of xampp in docker?

Running infinispan in docker on windows 10

I am trying to run the infinispan docker image on a Windows 10 machine with docker desktop for windows.
I wrote a small test Java program that connects to localhost:11222 using hotrod and accesses a cache.
The problem is that after the initial connect the client receives from the server a new address 172.17.0.3:11222 and it fails connecting to this address because this is a docker internal one and
docker desktop for windows cannot route messages directly to an internal container address.
Is there any workaround available in infinispan or on the windows machine ?
The simplest solution is to disable the handling of topology updates in your Hot Rod client:
infinispan.client.hotrod.client_intelligence=BASIC
More information about client intelligence here.
Note that this is not recommended in production: the client will ignore new servers coming up and it will keep trying to contact the servers in the initial server list long after they stop.

Rails application can't reach remote PostgreSQL server (proxy, VirtualBox)

I have a Windows 7 PC with Forefront TMG proxy. There is a VirtualBox virtual machine installed with Ubuntu 16.04 (64-bit) guest OS. I'm not a seasoned Unix-user, so I tried to configure Ubuntu's network through GUI window.
After several tries I wound up with these settings:

All works fine now. I can use browser and git and do various network stuff. But!
I have a Rails application, which uses a remote PostgreSQL database. When I start my Rails server, it throws this exception:
Puma caught this error: could not connect to server: Network is unreachable
Is the server running on host "this_is_the_host_url" and accepting
TCP/IP connections on port 5432?
(PG:ConnectionBad)
This applications works fine on the other PC with similar Windows 7 and VB Ubuntu, but without a proxy. Also I tried to reach the remote DB-server from my host Win7 with PGAdmin - all works fine, even with proxy. The issue is somewhere between my Ubuntu guest OS and my Windows host OS.
Should I configure proxy settings in Ubuntu in a different way?
Any other way to resolve this issue?
Traceroute shows this:
1 10.0.2.2 (10.0.2.2) 0.638 ms 0.577 ms 0.549 ms
2 10.0.2.2 (10.0.2.2) 29.369 ms !N 53.000 ms !N 75.644 !N
As I can get it, 10.0.2.2 is my host OS ip.
I searched through the web, but all I could get belongs to the opposite side: to reach to the proxied VB Ubuntu, not from it.

Amazon EC2 Ubuntu server - opencv::imshow() causes ": cannot connect to X server localhost:10.0"

So I am trying to run my code on an Amazon EC2 instance running Ubuntu Server 14.04 LTS.
I realized that my code is breaking with the following error when imshow() is called:
: cannot connect to X server localhost:10.0
I an connecting through putty and I have selected "Enable X11 Forwarding".
I can remove all imshow calls but I actually need to use them. Is there a way to enable this functionality while connecting to the EC2 instance through Putty ?
You also need to be running an X windows server on your desktop (where you're running putty). There are several available, and setup depends on which you choose. If you want a very easy solution, there's MobaXterm, which is an ssh client and X11 server combined. There's a commercial version and a free home edition (with some limitations).

Why my WAMPSERVER can't work?

I have some problem with my WAMP server and I downloaded from the official website. I wanted to use only for the local server (for Chrome), without WordPress, only for HTML/CSS/JS files. The servers (Apache, PHP and MySql) and the localhost webpage has оpen, but when I try to open my projects it's giving me the error:
This webpage is not available ERR_NAME_NOT_RESOLVED: and in details:
The server at problem%201 can't be found, because the DNS lookup
failed. DNS is the network service that translates a website's name to
its Internet address. This error is most often caused by having no
connection to the Internet or a misconfigured network. It can also be
caused by an unresponsive DNS server or a firewall preventing Google
Chrome from accessing the network.

Apache doesn't use all bandwith

I'm using apache 2.4.1 on windows and I'm trying to optimize my website www.xgclan.com loading speed with http://www.webpagetest.org.
I noticed that the download time is quite long in the report.
Today I downloaded the Windows 8 preview to my server as mirror, I put it on my apache server and tried downloading it with my home connection, the speed was only 500 KB/s.
My server has an 100 Mb/s duplex connection and task manager indicates that only 7% of the bandwidth is used.
I have 120Mb/s down at home and I ran a speedtest to make sure its not an issue with my home connection.
Downloading works fine on the server so I think its an issue with apache or windows server 2008 R2.
Can anybody help me so I can use my full 100 Mb/s upload?
This issue was caused by EnableSendfile on, after turning this off I was able to use the full connection speed.
