I am seeing very poor WAN performance on all of my (wan based) TSM backups. Due to the latency (40 msec typical) I normally only get about 20% of the available bandwidth used by a TSM backup. With EMC Networker I get over 90% utilization. I have already set all of these recommended options:
RESOURCEUTILIZATION 2 TXNBYTELIMIT 2097152 TCPNODELAY YES TCPBUFFSIZE 512 TCPWINDOWSIZE 2048 LARGECOMMBUFFERS YES Does anyone know of anything else that could help performance? Has anyone used a Riverbed accelerator for TSM backups? Tom
