            Bug ID: 281402
           Summary: [MediaRecorder/WebM]
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jean-yves.avenard at apple.com

The mkvmuxer writes data on average one or two bytes at a time and we append those bytes for a FragmentedSharedBuffer ; profiler shows that a lot of time is spent allocating the Vector that will contain this data and highly fragmented memory usage.

We should pack it up in block instead.
