Add a new configuration item called 'compressor_zstd_level' so that the Zstandard compression level can be tuned to the workload on a cluster. Fixes: https://tracker.ceph.com/issues/47425 Signed-off-by: Bryan Stillwell <bstillwell@godaddy.com>
The default compression level of 5 for Zstandard is too high for the majority of use cases since it requires too many CPU cycles. This patch switches the default to 1. Signed-off-by: Bryan Stillwell <bstillwell@godaddy.com>
