Description

  • I am on the latest Hyper.app version
  • I have searched the issues of this repo and believe that this is not a duplicate
  • OS version and name: macOS 11.4
  • Hyper.app version: 3.1.1
  • Link of a Gist with the contents of your .hyper.js:
  • Relevant information from devtools (CMD+ALT+I on macOS, CTRL+SHIFT+I elsewhere):
  • The issue is reproducible in vanilla Hyper.app: all plugins are removed

Issue

After updating to 3.1.x(stable), the launch time of hyper becomes significantly longer. In particular, in my computer it now takes 4 seconds to show $ while in 3.0.2(stable) it takes only 2 seconds, which is only slightly slower than iterm2 or original terminal. This issue also occurs when opening new windows and splitting windows.

Research direction

Reproduce the launch, new-window, and split-window delays on macOS 11.4 with Hyper 3.1.1, with all plugins removed, and compare them with Hyper 3.0.2. Done means identifying the cause of the increased startup time and confirming that these actions return to the earlier performance.
