Slow I/O issue in S4HANA 1610

Hi All,

We have S4HANA 1610 FPS02 system running on HANA 2.0 SPS01 database.

We are facing initial performance issue in our S4HANA system.

i.e., the issue we are facing is initial login to the system is taking more time(15 to 20 min) and also the first person who works on the server have to suffer for 5 mins+ to open every t-code that haven't been opened before, also not to mention the actions they do inside the t-code. But, when these transaction codes are run on the second occasion and further occasions, it’s fast and quick.

For this issue, SAP has highlighted that the I/O related parameter READ_MB_PER_S should have value of 200 MB/s instead of the current value of 9.17 MB/s(in our system).

Can you please help us in improving the value of this parameter. to 200 MB/s.
