java application on HP-UX performs very slow (much slower than on Windows , Linux, AIX)
Is there a way to diagnose socket I\O problems on HP-UX or maybe there is some possible limitations that can be configured? Maybe there is necessary JVM option? Any feedback from your side would be highly appreciated.
WeтАЩve tried to optimize JVM options according to http://publib.boulder.ibm.com/infocenter/wasinfo/v6r1/index.jsp?topic=/com.ibm.websphere.wsfep.multiplatform.doc/info/ae/ae/tprf_tunejvm_v61.html but didnтАЩt get any significant improvement.
JVM info:
Java HotSpot(TM) 64-Bit Server VM (19.1-b02-jinteg:2011mar11-16:46 PA2.0W (aCC_AP), mixed mode)
Java: version 1.6.0.10, vendor "Hewlett-Packard Company"
We use following instance:
OS: HP-UX (B.11.23)
Architecture: PA_RISC2.0W 64bit
Processors: 2
Total physical memory size: 4 088 MB
Swap size: 4 090 MB

There's just no way even the fastest PARISC system can beat X86 OS based Java period.
Let me guess -- your PARISC is likely a PA8800 or PA8900 system right? So something likely ~ 1.0 Ghz?
I know performance is not all about clock speed -- but c'mon -- PARISC are just old chips. Even earlier Pentiums and Xeons with HT (hyperthreading featurettes) are significantly faster than PARISC in certain compute workloads.

But I'm sure this must have been addressed in the IBM link that you mentioned (haven't read it to be honest).

Thank you for your reply. Yes, we are working in server mode. JVM switch it on automatically on HP-UX.

Thank you for your reply. I am pretty sure that we use old server. I will try to get it.
But unfortunately we cannot change it(

Re: java application on HP-UX performs very slow (much slower than on Windows , Linux, AIX)
What kind of PC/X86 environment were you comparing against?
I deal with this performance debacles/differences all the time. No amount of tuning on the old aging UNIX system (whose CPUs are a generation older than current) can beat even yesterday's X86 speedsters. Even today's current UNIX systems can still be beaten by today's X86 systems in head to head battle.
So you should really compare against a similarly configured system.
Good Luck.
