--> What type of drive you are using? How many each type?
--> Are you using both Pools?
--> How many VDG present in each Pool? I hope both pool contains VDG with different drive types.
--> Are you using Automated Tiering feature?
--> Are you using SSD read-cache?
--> Are you using Volume-affinity feature ?
--> What kind of performance issue you are facing? read or write? Sequential or random?
--> Was there anything running at the time of performance issue such as Scheduled backup, Antivirus, etc...?
--> What is the application you are running where you are facing performance issue?
--> What is Host OS, HBA firmware/driver version?
--> Host and SAN Switch up to date with respect to firmware or driver or any Microsoft Hotfix missing?
--> When you say performance issue what is you are checking and from where? is your expectation more IOPs or more throughput? both can't be achieved at the same time.
Please collect the Performance Statistical data 10 to 20 times (run one set of commands and then wait for 2 minutes) at the time the issue occurs:
# show controller-statistics
# show disk-statistics
# show host-port-statistics
# show vdisk-statistics
# show volume-statistics
Share the stat output here. Make sure any of the serial number of any MSA component shouldn't be visible in public.
You can also check best practice whitepaper and verify your setup,

Note: RAID 6 and RAID10 can't be compared with respect to performance measure. RAID10 is always give better performance over RAID6.
Hope this helps!
