rmi performance under tomcat
Hello all, I have an application which heavily uses rmi. Because the poor performance under tomcat, i tried some other app servers to compare. I came up with the following results: - tomcat 4.0.6 - websphere 5.0 - orion 2.0.2 - jetty 4.2.15 orion 1.2 sec websphere 1.2 sec tomcat 8.4 sec jetty 1.1 sec All tests ran under the same jdk (1.3.1_06), same machine, same configuration, default install etc. I know I use old jdk's and old tomcat version, but I have tried newer tomcat (4.1.28, 5.0) and newer jdk's (1.4.2), but that only showed slight performance gain. I used JProbe to find out what the bottleneck would be, it showed that 67% off all method time goes to java.rmi.server.RemoteRef.invoke and 20% goes to java.rmi.Registry.Lookup. Is it a known issue or known configuration issue, is there a way to speed up this performance? The test machine running is WinXp 1.8Ghz, 512Mb mem.

RE: dramatic performance differences on development machines
Hello all, I tried: - isolating code in a java class and running it on both machines, about same performance - running tomcat 4.1.29, bit faster but still ~15 sec. - changing network connection to full duplex, 2*faster but stil ~6 sec (should be < 1 sec). indicates network traffic could be a bottleneck - running websphere, performance ~600 ms. - changing java version 1.3.06 to 1.4.1, no reasonable effects - eliminating all services, no effect The tested machines: (the machine which performance is fast, a dev. client) P4 2.4Gh, 512MB memory, 60Gb harddisk (the machine which performance is slow, the server) P4 2.4Gh, 1Gb memory, 10Gb harddisk (the machine which performance is slow, a dev. client) P4 1.8Gh, 512MB memory, 40Gb harddisk I see tomcat running high on processor performance, peeks in processor performance are the same as peeks in the network traffic. But, when running everything on one box, it is also slow (so network should not be an issue). Also, the developer on the fast machine noticed that when getting code from CVS from other developers, his system slowed down signifficant too, but I have no clue what too look for with this indication. I hoped to hear a some kind of, hey look into this or look into that, did you look here, but unfortunattaly there's not. It is also a complex problem with many factors that could be the cause (network?, language settings os?, system settings?, file system?, foreign processes which interfere?, ...). If anyone has got a clue i would be glad too here, meanwhile i'll go look furher looking for a solution / cause.

No, it's a one processor machine. Question, could it be that jsp:include 's are very slow and that this is causing performance issues?

RE: dramatic performance differences on development machines
A lot of network traffic, database lookups, rmi is going on, but i even tested that by placing code on the mediasurface server with oracle (placing all on one box), and so limiting network traffic, but same performance issues occured. I tested on websphere and everything is speedy (so, its not the code). It should be something in the system, a configuration which influences tomcat performance dramatically and not webspheres performance, but what i can't figure out what this could be.

Hello Nikola, Machines are not identical, the fast machine has different specs (less memory, less disk space and less cpu) then the slow machine (this one has better specs). One hint we've got is the carachter encoding in which the file is saved, but it seems to me this cannot be the problem... Sure, heavy artillery can be used, but i don't think that would lead us to a solution, also because the machine with lesser specs serves better, and we use the same tomcat version, same settings and same jdk version.

On 1 dev. machine the performance is approx. 400 - 1000 ms. a page, on another 8000 - 14000 ms. I've copied the complete tomcat directory to the slow dev. machine, running the same jdk, same os and same patches, but still the machine performance is slow.
