Hello Peter,

It is problematic to convert these 300 to native RPGLE
which I know would perform well.

What do you mean by native RPGLE? Using RLA? Using embedded SQL?

However, if the same transaction is repeated then the
same result can be returned in about 5 seconds.

What if the Job running the SQL were left running? Say waiting for a request to be placed on a queue?

he can easily create a script that runs all 300 statements on

SQL server in just a few second with no performance problems.
Why is that?

Not sure. Could he be using an asynchronous interface, which returns quickly, even though SQL Server continues to crunch in the background? I used that trick in the past.
