https://community.hpe.com/t5/operating-system-hp-ux/rpc-performance-problem/m-p/5281833#M607307 Hi,<BR /><BR />We have a RPC performance problem on HPUX 11.31 server where our application takes considerable time to send data to client systems. Application trace logs show that server side rpc_sendreply() takes about 4 seconds to send across less than 100 kB of data. The thick-client application runs on Windows systems.<BR /><BR />The same application on HPUX 11.11 works as expected for the same data and shows no performance drop. <BR /><BR />IPFilter is disabled on the 11.31 server. Are there some additional features on 11.31 that monitors RPC communication that could slow down the process? Is there anything we can check on the server OS (maybe network interface settings)? <BR /><BR />Thanks<BR /> Wed, 11 May 2011 07:27:22 GMT Medha Rane 2011-05-11T07:27:22Z https://community.hpe.com/t5/operating-system-hp-ux/rpc-performance-problem/m-p/5281833#M607307 Hi,<BR /><BR />We have a RPC performance problem on HPUX 11.31 server where our application takes considerable time to send data to client systems.
