            Bug ID: 200486
           Summary: IndexedDB deleteIndex() is very slow
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jleis at prometheusgroup.com

Compared to other modern browsers, the delete performance of indexeddb records is very slow on webkit/safari.

Here is a jsfiddle that demonstrates the issue.  https://jsfiddle.net/pzur4mtb/3/

Using the same macbook pro, mojave 10.14.6, safari 12.1.2.

On Chrome, the delete process takes around 2 seconds.
On Safari, it takes upwards of 16 seconds.

The issue can be replicated on all devices that support safari.

(I tried to test on webkit archive directly, but it errors trying to load sqlite files)
