Can the use of source-side disk cache theoretically reduce the DDB lookup of data protection jobs? Clients and MA are on the same LAN.

If you enable this on a Client, it will create a small database for local signature lookups before querying the MA. Technically, yes, it would reduce lookups against the MA’s DDB.
However, a Client and MA on the same LAN is not the typical use-case for this feature. If the Client’s cache is on slow disk, it won’t perform as well as the MA’s DDB. Combine with the typical low latency you should see on a LAN and it could potentially be slower than using the MA.
If your Client was talking over a WAN to the MA, it might be worth considering.
