MINOR: compression: optimize memLevel to improve byte rate

Browse Source 
Decreasing the deflateInit2's memLevel parameter from 9 to 8 does not
affect the compression ratio and increases the compression speed by 12%.
Lower values do not increase transfer speed but decrease the compression
ratio so it looks like 8 is optimal.
