In the dsm.opt file, I also set my tcpnodelay to yes, Txnbytelimit to 25600 in winnt, and in w2k machine I set my txnbytelimit to 131072 but my RAM is 4 GB.

I have AIX, W2K, NT and NetWare. I had already changed the configurations at the server following your tips but I cannot do it at production servers, at least not today.
