#echo "xs_trans_sync - This is the number of meta-data transactions which waited to be committed to the on-disk log before allowing the process performing the transaction to continue. These transactions are slower and more expensive than asynchronous transactions, because they force the in memory log buffers to be forced to disk more often and they wait for the completion of the log buffer writes. Synchronous transactions include file truncations and all directory updates when the file system is mounted with the 'wsync' option."

These transactions are faster and more efficient than synchronous transactions, because they commit their data to the in memory log buffers without forcing those buffers to be written to disk. This allows multiple asynchronous transactions to be committed to disk in a single log buffer write. Most transactions used in XFS file systems are asynchronous."

#echo "xs_log_blocks - This variable counts (in 512-byte units) the information being written to the physical log partitions of all XFS filesystems. Log data traffic is proportional to the level of meta-data updating. The rate with which log data gets written depends on the size of internal log buffers and disk write speed. Therefore, filesystems with very high meta-data updating may need to stripe the log partition or put the log partition on a separate drive.
