We are facing a performance problem with a AIX / Power7 LPAR running WAS/ Portal. to try to slove the problem we used a benchmark to compare the LPAR with PC performance, and we found out that the PC (Intel i7) is much faster.
Here is our results :
AIX Dev LPAR : 250 Mflops (1 core)
Win XP / Intel i5: 752 Mflops (1 core)
Linux / Intel i7 : 1366 Mflops (1 core) // 5-6 faster than AIX !!!
We have done all the JPA (Java Performance Advisory) and the number didn't changed, is this normal ?
