Hey! Yes you are correct! We have both been upstreaming changes to the main GVisor repo. However, in order to work within our own infrastructure we had to make various changes that we explain throughout the article (Open TCP connections, multiprocessing, unix sockets etc).

Also in our benchmarks we seem to perform better than Modal by ~20% in 4/6 workloads we tested and have a lower spread of results meaning you get more consistent results. However the same fundamentals still apply -> how can you move storage into memory as quickly as possible
