When I switched to Linux (Kubuntu 14.04) it worked immediately. Could it also depend on the java version? I'm using OpenJDK under Linux now. ___ Support mailing list Support@freenetproject.org http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://emu.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:support-requ...@freenetproject.org?subject=unsubscribe

Are you sure Freenet is actually running? To start it, open a terminal, manoever to the freenet directory and type "./run.sh start" (without quotes). ___ Support mailing list Support@freenetproject.org http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://emu.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:support-requ...@freenetproject.org?subject=unsubscribe

Are success rates different? Datastore sizes are different: 3,2 TiB (320 GiB occupied) on the slower machine, 500 GiB (60 GiB occupied) on the faster one. Success rates are much different throughout, ranging from 31% vs. 0.1% in favor of the faster machine (client cache CHK) to 1.2% vs. 4.8% (store CHK) with the slower machine ahead in this case. Can't see a pattern. But please don't waste too much time on this, I just thought there might be a simple answer. I will search for a Linux tool to check the I/O queue depths of the slower harddisk and report back if that seems to be the cause.

[freenet-support] Which indicator determines general freenet performance? CPU bottleneck or not?
Hello, which indicator is more important for the overall performance of Freenet: The input/output rates or the access rates? Or is it something else? I'm asking because I'm currenty running a dedicated Freenet machine on Kubuntu 14.04 and I wonder if I still have a CPU bottleneck. Hardware is a Celeron G1620 (Ivy Bridge, 2x 2.7 GHz), 4TB 3,5'' 5900rpm HDD, had upgraded from a much slower AMD E-350 (2x 1,6 GHz, less IPC). The system info says the CPU is rarely above 50% load. But I get slower input/output rates than on a faster machine (i5-2500k @ 4x 4.0 GHz, Windows 7, system on a SSD, Freenet on a 7.200rpm HDD) with a test install of freenet. It's roughly 150KiB/s vs. 300 KiB/s. Access rates do not differ that much: About 15/s vs. 17/s.

Thanks for the answer. Played around with the settings on a fresh freenet install, but I do not really know what I'm doing... This seems to work more or less: wrapper.java.initmemory=60 (default) wrapper.java.additional.4=256 wrapper.java.maxmemory=1536 On the stats page, 1,45 GiB are allocated for Java and 1,30 GiB are in use. I left alone the MaxPermSize setting, which seems to point to another variable: MaxPermSize=wrapper.app.parameter.1=freenet.ini Still testing, had some additional stability problems because VirtualBox seems to have problems (BSODs with hardware virtualization and two CPUs in den VM). I successfully started a copy of the original 400GiB node and set the datastore size to 3000GiB. But after half an hour it still says "Datastore(CHK-cache) resize in progress: 0/6137772". Hmmm. I'll check back later. ___ Support mailing list Support@freenetproject.org http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://emu.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:support-requ...@freenetproject.org?subject=unsubscribe
[freenet-support] 3TiB-Node: Installation fails with Java out of memory error
Hello everyone, I had successfully run a 400GiB-Node in a Windows 7 x64 environment, running as a virtual machine in VirtualBox with 6GB RAM. Now I moved the whole installation to a larger harddisk and tried to increase the datastore size to 3TiB. This results in a java out of memory error. This is from my wrapper.log: INFO | jvm 1| 2014/04/14 17:08:17 | Initializing SSK Datastore (46033289 keys) INFO | jvm 1| 2014/04/14 17:08:17 | WrapperManager Error: Error in WrapperListener.start callback. java.lang.OutOfMemoryError: Java heap space STATUS | wrapper | 2014/04/14 17:08:17 | Filter trigger matched.

After a few more error messages freenet shuts down completely. Same problem with a new & clean install of freenet. Memory settings from my wrapper conf: wrapper.java.initmemory=256 wrapper.java.additional.4=-XX:MaxPermSize=256m wrapper.java.maxmemory=1024 Did not work with the original settings, too. Any idea what I could do?
