Write times and Write pending correlation

Hello guys,

i am trying to make sense out of this situation. Why during the time when i have over 20000 write pendings (9:15am), average write times is good (less than 20ms), yet when write pendings are very low (around 10:15am), i have almost 90ms write times. Write pending threshold is around 55000 per devices (5% of total system write pending slots). This is 100% write workload.  Any clues ?
