HI All,

we have HADR running for 6 SAP systems with ASYNC,

on SAP BW we have performance issues, when ever HADR is ON and in peer status, process chains are running very slow, they are taking 3 hour more that normal time,

IF HADR is switched OFF, they are running OK,

no network issues,

logfile size was 1GB we reduced it to 640MB, we can not go beyond this value ,

when we have performance issues StandByRcvBufUsed is not even 10%
