we have a strange thing here: two XENified OES(Linux)2 SP1 boxes on same hardware. ServerA with NSS, Server B without NSS but with Groupwise installed. TSA/SMDR configured the same way, except the GW-switches as in the documentation on Server B. Result: using tsatest, Server A shows marvellous performance backing up whatever filesystem I want (NSS/EXT3), ServerB has more than a poor performance I ever saw, which means in this case 3GB/min on A and 5MB/min on B. Other tools like iostat show equal results for the two servers so the TSA is the one to blame I think.
Any ideas??
