The console stays fast for busy accounts
Home, Usage & billing, a sandbox's own page and Networking no longer slow down as an account's history grows: on an account with 100,000 sandboxes in a month, Home opens in under a tenth of a second instead of 1.5 s, and Usage & billing in 0.15 s instead of 1.2 s. Older pages of the audit log, and the log filtered to one kind of change, open as fast as its first page. See the audit log.
