Question Internet speed -- Networks & Linux ?

[simmerskool]

This could be a linux question or a VMware question, or a browser question -- not sure where to post this question.
Running Zorin (Ubuntu) in VMware. Today I noticed reactions (page loading) in firefox seemed a tad sluggish. I currently have 2 windows of firefox open each with several tabs open, but RAM usage has not varied all day, running at 20%. I have some reading to do yet, so have not closed firefox. Went to my mac-mini and using safari opened it to my Ubiquiti router where I can test the connection speed directly from/to the router. It tested at 930 dn / 40 up which is about as good as it gets here (my ISP plan is 1 gig down 40 up). Then tested in VMware Zorin with firefox using Speedtest from a server in more or less same location and tested only 87 dn / 32 up. Just test on win10 Host with firefox & speedtest 567 dn / 39 up. Was NOT running vpn. Can anyone explain why VMware linux down speed is so comparatively slow? Later tonight I will close linux browers and reboot and test on linux again to see if this is some browser-linux issue. Will update later. Thanks.

There could be several reasons for the slow internet speed in your VMware Linux. It could be due to the network adapter settings in your VMware, Firefox's cache, the resource allocation to your virtual machine, or even a bug in the Linux kernel. I'd recommend you to check and adjust the network settings in VMware, clear your Firefox cache, and ensure your VM has enough resources. Also, keep your Linux and VMware updated. Looking forward to your update.

Yes I agree with everything you just said. most likely in my mind is firefox cache. What network adapter setting do you recommend for VMware?

For optimal performance in VMware, it's usually recommended to use the VMXNET3 network adapter as it provides more features and better performance compared to other types. However, you need VMware Tools installed for this. Also, ensure that the network connection is set to NAT if you want your VM to share the host's IP address.

I need to research VMXNET3. I do see VMware Tools on Guests running win10 OS but not obvious that Zorin is running / using VMwTools.
I did clear firefox cache and reboot zorin and used speedtest webpage again, and basically the same "slow" results. I tried various things with firefox like turning off extensions with a minimal increase from 110 dn to 135 dn. Also now I'm aware that apps opening and closing seem sluggish too.

In the following sitting, try to select "Bridged", and enable "Replicate physical network connection state".

IIRC that slowdown was with Zorin Pro 17.2, not sure if was an update or what, but noticeable slowdown. After that is when I tried to install kfce4 on Zorin gnome and borked Zorin. BTW my VMs use Bridged network. MX is very fast no slowdowns seen so far. PS this hardware has lots of RAM so typically give VMs 16 gb RAM and 8 gb of graphics & 6 cores cpu. So VM have resources. Host win10 seems not to miss that allocation to VM. I even give the Harmony AV VM 32 gb RAM. I think that Zorin Pro is just heavy.

From my previous experience, installing more than one DE on the same distro will make problems, and trying to remove or replace DE will break a lot of functionality, it happens for me before, so it is not recommended, some distros come with multi DE by default like Voyager, this is a different situation because the developer know how to manage different component and how to eliminate conflicts.
MX in general is faster and lighter than Zorin because it is based on Debian and use Xfce, in general you will find this combination lightweight always.

yes I learned that lesson, but also recall and confirmed by a linux friend that in remote past CentOS had option to boot Gnome or KDE. Now happy using & learning xfce4 on MX.

In the installation phase, there are distros like Debian and openSUSE which give you the ability to choose the desktop environment you want to use, they basically install the kernel and the core system, and after that install the desktop environment you select, but changing after installing is what makes problems, because it will let remnants on the system that will conflict with other desktop environments components, I remember trying to install Budgie DE over Ubuntu to try it, after that I liked it that I want to remove Gnome from Ubuntu and Boom, my system didn't reboot at all.
