Please, kill Jira and Confluence. I hate Atlassian tools so much. The user interfaces are sluggish no matter the hardware you're using... it's a shame it became almost a standard in our industry.
I just opened a view mode page in confluence, and it made >400 calls until fully loaded. ~80 XHR calls and >300 js files being loaded, in what world that is acceptable?
Indeed it is a shame that they still a thing.
