But a branch of a desktop is an entire running workspace, and cloning it with today&rsquo;s tools means a synchronous checkpoint/restore on the critical path of every speculative step. We built <strong>TClone</strong>, a workspace-versioning substrate that makes a branch runnable immediately by sharing memory and filesystem state copy-on-write and pushing durable checkpointing off the fast path. TClone clones a live workspace <strong>up to 4.9x faster</strong> than VM snapshots and <strong>3.4x faster</strong> than stock CRIU, and cuts end-to-end agent task latency by <strong>up to 3.7x</strong>. <br/><br/> <a href="https://mlsys.wuklab.io/posts/tclone/" target="_blank">Read More&hellip;</a>
