Thanks a lot for reply.

I complied the test program on both the servers and executed the corresponding binaries on both machines. Also, no other application is running on any of these servers.

Additionally, I tried one more experitment and found the following results.

Attached Program (ABC.cpp) is compiled by - /usr/sfw/bin/g++ -g -Wno-deprecated ABC.cpp -lpthread and Run by - time -p ./a.out

High Performance Architecture (kansparc54144) - root/labbws54144

MY CONCLUSION:
High Perf Arch perform good in case2 but bad in case1 (???).

I don't understand this behavior . could you please provide some information on the above behviour.
