Del: We have been using these settings as our defaults. Is our TCPWINDOWSIZE too large?
RESOURCEUTILIZATION 2 (we increase this up to 10 for some WAN backups) TXNBYTELIMIT 2097152 TCPNODELAY YES TCPBUFFSIZE 512 TCPWINDOWSIZE 2048 LARGECOMMBUFFERS YES Also we never use compression because our storage folks believe it will foul up the de-duplication that happens on our Data Domains??
