java server mode vs. client mode
I posted this on the struts list this morning, but it might get better answers here. I was reading the stories here: http://www.sys-con.com/story/?storyid=45250 http://www.kano.net/javabench/ Summary: Java in server mode is faster than C++ in the benchmarks run. Java in client mode is much more iffy, sometimes faster, sometimes slower, and sometimes the same. So my question becomes - does anybody have any experience running their Tomcat jvm using the -server option instead of letting it default to client? Based on what the tester says, the only downside of running the jvm in server mode is a longer startup time, but the Java code still beat C++ even with the longer times, so it can't be too bad. So anybody have any experience/thoughts on this? Thanks, Matt Bathje - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: java server mode vs. client mode
this has been mentioned countless times on the mailing list and I have tons of numbers comparing client to server in my article on the resources page of tomcat. if you want hard numbers, I would suggest look at the article, or run some stress tests on your own apps. a quick test will give you hard numbers to prove/disprove the benefit/non-benefit of running in -server mode. i hope that helps peter Matt Bathje [EMAIL PROTECTED] wrote: I posted this on the struts list this morning, but it might get better answers here.

Re: java server mode vs. client mode
Thanks for the pointer to the article, don't know why I didn't just think to look their in the first place. I was sure it was something that has been mentioned on the list before, but I wasn't able to find a way to search for it that yielded good results. Thanks again for the info!

[OT] Re: java server mode vs. client mode
Yes, I understand that it may not be completley accurate, but I was less interested in the Java/C++ comparison than the client/server mode comparison.

Re: java server mode vs. client mode
ahh gotta love benchmarks. the only valid benchmark is your own application, which you've tuned. all other cases are seriously error proned or not applicable to real applications. peter Eric VERGNAUD [EMAIL PROTECTED] wrote: le 16/06/04 21:50, Matt Bathje à [EMAIL PROTECTED] a écrit : I posted this on the struts list this morning, but it might get better answers here.

No one can really believe Java is faster than C or C++, because Java is itself written in C and C++. isn't there a hardware JVM implementation? maybe running on that, Java C++ :D __ Do you Yahoo!?

Re: java server mode vs. client mode
At first: If I'ld write a C++ compiler with Perl, this doesn't mean that it will generate code slower than Perl scripts:) Then: Exhaustive optimization techniques (like loop expansion, disabling array bounds checking, etc.) really make your code faster in ANY case, BUT small amount of generated code may fit your processors cache, some jump may be converted to short jumps, etc.. So, generally speaking, more optimized code shall run faster, but it's bigger. Huge amount of code may even seriously decrease amount of free RAM, so more swapping will occur. AND ... if you do really meaninglessthings in your code, then there's a chance that optimizer will not eliminate this code, because it cannot generate OPTIMAL code. This is, mathematically speaking, twice a NP-hard problem. First when generating code, second when testing it's speed. I recommed using -server hotspot. Look at name... S E R V E R. I'm not sure guys from Sun randomly named it this way :) - Original Message - From: Eric VERGNAUD [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Thursday, June 17, 2004 12:12 AM Subject: Re: java server mode vs. client mode le 16/06/04 21:50, Matt Bathje à [EMAIL PROTECTED] a écrit : I posted this on the struts list this morning, but it might get better answers here.
