packets bypass compres Number of packets that were not compressed because they were too
small (<128 bytes).
packets not compressed Number of packets that were not compressed because the packets
are expanded rather than compressed.
compression ratio Ratio of compression and decompression of packets presented to the
compression algorithm that were successfully compressed or
decompressed. This statistic measures the efficiency of the
algorithm for all packets that were compressed or decompressed.
overall Ratio of compression and decompression of packets presented to the
compression algorithm, including those that were not compressed
due to expansion, too small. This ratio indicates whether the data
traffic on this interface is suitable for compression. A ratio of 1:1
would imply that no successful compression is being performed on
this data traffic.
