Hello,

One of my IOC hosts ~20k records, when restarting it, sometimes it may throw "scanOnce: Ring buffer overflow" messages, which leads to some incorrect statistical calculations.

I guess this might come from:

1. autosave, which will trig a bunch of crowded restoring, is that possible to slow down the process?
2. It's too many records in one IOC, if so, what would you recommend? Dose splitting it into multiple ones help?
   

Please correct me if my understanding is wrong, and I appreciate any sharing on resolving this issue.

Thanks,
Tong
