Windows/VirtualBox performance
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Performance when using Windows/VirtualBox is by default abysmal, as
AVX/AVX2 instructions are deactivated (see e.g.
`here <https://stackoverflow.com/questions/65780506/how-to-enable-avx-avx2-in-virtualbox-6-1-16-with-ubuntu-20-04-64bit>`_),
which causes a dramatic performance loss. Deactivate Hyper-V/Hypervisor
using::
bcdedit /set hypervisorlaunchtype off
DISM /Online /Disable-Feature:Microsoft-Hyper-V
Performance can be further increased when compiling MP-SPDZ yourself:
::
sudo apt-get update
sudo apt-get install automake build-essential git libboost-dev libboost-thread-dev libntl-dev libsodium-dev libssl-dev libtool m4 python3 texinfo yasm
git clone https://github.com/data61/MP-SPDZ.git
cd MP-SPDZ
make tldr
