          Priority: medium
            Bug ID: 62188
          Assignee: spice-bugs at lists.freedesktop.org
           Summary: Automatically disable compression for local-only
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: zeenix at gmail.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: server
           Product: Spice

For local-only case (client and server on the same machine), compression is
quite redundant as we can assume very high bandwidth so no need to waste CPU
time on compressing/decompressing.

In theory we should first address bug#62187 but in practice (testing with
varrious OSs), I have observed that we don't really get lipsync when playing HD
videos fullscreen (pretty common scenario now a days). I suspect its because of
decoding of video/audio in the guest combined with compression and
decompression of SPICE stream on the same CPU and CPU being unable to manage
it. Before you ask my host:


CPU: Intel® Core™ i5 CPU M 540 @ 2.53GHz × 4
RAM: 8G
