Fran, one parameter you can change is Bufpoolsize on the server. for 1GB of real RAM you should put it to 131072. the other thing is to turn compression off, in a single client, fast client, fast server, fast network it gives better performance. then on the AIX server try no -o rfc1323=1 no -o thewall=131072 no -o sb_max=1310720 use vmtune to view virtual memory settings. if the filesystem is jfs you should put maxpgahead to maximum (-R256). stop virtual memory paging by modifying minperm/maxperm parameters (default is -P80, lower it to -P50 but watch minperm).
on the client check if compression actually makes files bigger, and check how many retries there are when sending data to server. put TxnGroupMax to the maximum (256) if retries are rare. you can raise TxnByteLimit (maximum is 2097152). MoveBatchSize should be 1000, MoveSizeThresh 500 (2048 for TSM 5.1), set ExpInterval to 0. then pray...
