Since our last measurements, startup time in Zed had regressed quite significantly. This was due to several issues: - We were loading IBMPlex, which we're not really using in the UI. - Images were being parsed in the foreground, thus blocking the main thread - Language models (for semantic index and assistant) were being loaded in the foreground, thus blocking the main thread - Interaction with the keychain was blocking the main thread In addition to these, with this pull request we will now deserialize the items for a pane in parallel, as opposed to doing so sequentially. All combined, when running the zed binary directly this brings startup time from ~350ms to ~210ms on my machine. Release Notes: - Improved startup time.
