Thanks for the answers Bob! >Try increasing the maximum heap via the JavaMem line in Flaunch.ini to e.g. >"JavaMem=256" for 256 MB maximum, this should help somewhat. (Java's default gc >likes to wait till it has almost no heap left before it bothers to collect, at >which point it can thrash and do so very slowly.) > > That's just the problem. I have 512MB of RAM and with various applications running concurrently [Palm Desktop, Thunderbird, Mozilla, jEdit, Apache HTTP, Sun J2EE RI, MySQL, I2P, Tor, Gaim, GoogleTalk, Prime95, WorldCommunityGrid, BOINC, electricsheep, etc.] there's no more left to hand over to Freenet. All the applications were well-behaved until Freenet got installed - now my machine is a *turtle*. The use of 1.5 however is a huge improvement.
Before anyone asks - no Freenet isn't the last straw. I've tested that possibility by stopping some of the other servers & applications but it doesn't make a difference. I've isolated the pigginess to Freenet! >Not only should it, it's supposed to :( >Can you please post exactly what versions of 1.4 / 1.5 you have installed? > > Hence my surprise. :) I have Java 1.5 Update 5 (1.5.0_05-b05) & Java 1.4.2_09 (1.4.2_09-b05). I have both the JDK/SDKs & the JREs for each version. I've setup my environment such that a "java", "javaw" or "javaws" at the command line starts up the 1.5 version of the apps. Could my Windows registry be corrupted? What keys' existence should I check for? The paths are as follows Java 1.5 JDK: C:\java\se\sdk\1.5.0_05\ Java 1.5 JRE: C:\Program Files\Java\jre1.5.0_05\ Java 1.4 JDK: C:\java\se\sdk\1.4.2_09\ Java 1.4 JRE: C:\Program Files\Java\j2re1.4.2_09\ >Hopefully the wininstaller can be dropped for the proposed amazing java thing >maintained in core by the time 1.6 is mainstream ;) > > I'm curious, what amazing java thing? >>> 2) Is it possible to pass options to the JVM (e.g. AggressiveHeap, >>> DisableExplicitGC, server, etc.) via the system tray icon?

I do Java development and don't want to change the JVM defaults on a system-wide basis as users (of applications I work on) might end up with poor performance if I allow the JVM to "hide" my bad programming practices during development. A related question: Since the windows launcher can't pass options to the JVM, does anyone know if there is a service wrapper (for Windows XP) available for Java applications? I can then configure the service wrapper with the necessary JVM options & have freenet run 24/7 as a Windows service on all workstations under my control? Thanks, Ashton
