[JBoss-user] performance on linux/windows
Hi.. I want to know one thing. My question, JBoss on windows/linux, which gives better performance? whether windows or linux. Pls reply back as early as possible. Thanking you with regards Tejesh
Re: [JBoss-user] performance on linux/windows
I think that the difference is litte if you use the best jdks on both platforms (ibm/sun 1.4 for linux), but linux is far more stable and easier to work with than windows. We run on SuSE.de. And I think linux has a better memory/swap/disk-handling than win. It utilizes most of the memory for buffers, while win might let the memory be free (i.e. don't use it).

Re: [JBoss-user] performance on linux/windows
with shame i have to agree with this, according to several performance tests w2k has better thread handeling than linux (2.4 kern) at the moment mvh karl øie On Friday 07 June 2002 13:35, Maris Orbidans wrote: > and what about threads ? > > > > IMHO JRockit is the best VM for JBoss > > Its free > > http://www.jrockit.com > > > Maris > > > -Original Message- > > From: Marius Kotsbak [mailto:[EMAIL PROTECTED]] > > Sent: Friday, June 07, 2002 2:00 PM > > To: [EMAIL PROTECTED] > > Subject: Re: [JBoss-user] performance on linux/windows > > > > > > I think that the difference is litte if you use the best jdks on both > > platforms (ibm/sun 1.4 for linux), but linux is far more stable and > > easier to work with than windows.

It seems like it is free now. I will give it a try.

Re: [JBoss-user] performance on linux/windows
Greetings. Which 2.4 Kernel? And did you reset the Thread/Process handles in the Kernel? Above 2.4.10 (I would STRONGLY RECOMMEND 2.4.18 for this, btw), a new thread manager and virtual process manager was put into the Linux Kernel. The gotcha's; 1) Many Distro's, including SuSE, patched OUT the new thread manager in 2.4.17 and below (there were some bugs) 2) Linux Kernels ship with the following maximums by default; Max Threads/Process = 64; Max Processes/System = 1024 These defaults cause serious performance degradation of JBoss on Linux systems starting at around 150-200 concurrent users. I boosted test box up to Threads = 8192/Process=8192, have not had any problems, and the box screams. (Have not actually deployed into production yet, sorry). The reason that the defaults are so low is that for end-users, and development boxes, this prevents runaway forkers from taking down the system. This does cause an issue for production servers, however. -Steve Karl Ãie wrote: > with shame i have to agree with this, according to several performance tests > w2k has better thread handeling than linux (2.4 kern) at the moment > > mvh karl e > > > On Friday 07 June 2002 13:35, Maris Orbidans wrote: > >>and what about threads ? >> >> >> >>IMHO JRockit is the best VM for JBoss >> >>Its free >> >>http://www.jrockit.com >> >> >>Maris >> >> >>>-Original Message- >>>From: Marius Kotsbak [mailto:[EMAIL PROTECTED]] >>>Sent: Friday, June 07, 2002 2:00 PM >>>To: [EMAIL PROTECTED] >>>Subject: Re: [JBoss-user] performance on linux/windows >>> >>> >>>I think that the difference is litte if you use the best jdks on both >>>platforms (ibm/sun 1.4 for linux), but linux is far more stable and >>>easier to work with than windows.

Re: [JBoss-user] performance on linux/windows
It is not about performance it's about manageability in production. Widows is simple too much of a pain to manage on a large scale. -dain Tejeshwar wrote: > Hi.. > > > > > > I want to know one thing. > > My question, > > > > JBoss on windows/linux, which gives better performance? > > whether windows or linux. > > > > Pls reply back as early as possible. > > > > Thanking you > > > > with regards > > > > Tejesh > ___ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas - http://devcon.sprintpcs.com/adp/index.cfm?source=osdntextlink ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

Run a slow fullscreen-connection (like pcanywhere) to the win-server? It will certainly be slow. Or log in with telnet (which is insecure) and try to do in on the dos-command line? What if 2 pepole need to access it at the same time? With jboss running on linux (or similar OSes), you can just log in with ssh, check logs, fix config/change code, compile and deploy it, restart jboss etc. without problems from anywhere (including public web terminals if you have a web-ssh client set up) in a secure way. > > Tejeshwar wrote: > > > Hi.. > > > > > > > > > > > > I want to know one thing. > > > > My question, > > > > > > > > JBoss on windows/linux, which gives better performance? > > > > whether windows or linux. > > > > > > > > Pls reply back as early as possible. > > > > > > > > Thanking you > > > > > > > > with regards > > > > > > > > Tejesh > > > > > > ___ > > Don't miss the 2002 Sprint PCS Application Developer's Conference > August 25-28 in Las Vegas - >http://devcon.sprintpcs.com/adp/index.cfm?source=osdntextlink > > ___ > JBoss-user mailing list > [EMAIL PROTECTED] > https://lists.sourceforge.net/lists/listinfo/jboss-user ___ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas - http://devcon.sprintpcs.com/adp/index.cfm?source=osdntextlink ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
