VMWare running ridiculously slow (hexbear.net)

submitted 5 months ago by [email protected] to c/[email protected]

I'm in a class that requires I use VMWare virtual machines, however it's running very slow. I had a meeting with my professor to try and trouble shoot why but we both can't seem to find a reason.

I got plenty of ram, I shut down a few programs that seemed to be causing my computer to run slow and made sure the VMs were in my actual drive not the cloud but is still very sluggish.

Make sure you have virtualization enabled in your BIOS, without it you're going to be doing software emulation which is not very fast.

Make sure you disable hyper visor mitigation from the advanced settings. It sacrifices significant performance to help prevent data leak attacks between the VM and the host, which typically you don’t care about unless you’re a cloud hosting provider.

If that doesn’t work, try switching to one vCPU core. I’ve seen systems that have trouble scheduling multiple at once.

I've seen other people say this elsewhere but it seems like they took away the option to do this on the newest version of VMWare. At least I don't see it anymore.

Ah, that’s a shame. I’m not sure how to help find that because the option appears for me.

What if you downgraded one version?

I had to find a download first and VMWare seems to be really cagey about where the fuck you can find their software

You can definitely find an older version of pro on some pirate sites, or if you're just looking for player it looks like they have it here

Is VMware an actual requirement? There are other virtual machine solutions that are much better. If you're on windows I would recommend hyper-v

That's what the professor wants us using but I may be able to get away with using something else, kinda depends if the files she's giving me are compatible with other VMs

What are these virtual machines running? You might be missing some software package or library on your client machines so look into that.

The one I'm using right now is just a Windows 10 environment with some cybersecurity software on it
