Hi,

As my old server has some hardware issue i took full backup from xtrabackup ver. 2.3 and restored in new server. Both old and new server has exactly identical specs.

Next Day, when i started my activities on new server i came to know that INSERT speed is highly impacted and I found 3.34 %iowait from iostat command.

%util also shows 99% at the time of insert.

Please help me to understand issue
