The invention discloses a performance regulation and control method, device and equipment, a program product and a storage medium, belongs to the field of controller performance optimization, and is used for solving the problem that IO performance and
RAID card performance cannot be considered at the same time by adjusting interrupt aggregation number to balance IO efficiency and
CPU load rate. According to the method, the real-time load rate of the CPU of the
RAID card can be obtained, and the interrupt aggregation number of the external hard disk of the
RAID card is adjusted according to the comparison result of the real-time load rate and the load rate upper limit, so that the interrupt aggregation number is reduced on the basis that the real-time load rate is controlled
not to exceed the load rate upper limit, that is, the interrupt aggregation number can be adjusted, and therefore, the real-time load rate of the external hard disk of the RAID card can be reduced. On one hand, the real-time load rate of the CPU is controlled to be lower than the load rate upper limit, on the other hand, the interrupt aggregation number is reduced as much as possible, the IO efficiency and the
CPU load rate are balanced, the IO performance and the RAID card performance are both considered, and the user experience is improved.
