Hello,

Thanks for the replied. I have downloaded new RAMMap ver 1.52 and it work on Windows 10.

On Process tab of RAMMap, firebird.exe took 2,183,484K.
On File details tab, database file took 2,603,168K.

Does it means, FileCached worked? It if worked, how come, the disk kept spinning when query runs?

Thanks & regards,
Anto.
