Tcp send receive buffer size for fabric similar to XDR

How Developers Are Using Aerospike How Aerospike Works

Hi All,

Similar to XDR, I set tcp send, receive buffer size to 5, 15MB respectively for fabric sockets.

I could see 5% increase in IOPs after below change.

I would like to know why this change was not made available for fabric sockets?

Thanks for the info. Let us review your findings.

The init scripts do configure these settings for fabric sockets. Maybe you aren’t using these scripts?
