I always got these out memory errors when I tried to run a 3TiB node under 
Windows 7 64-bit, regardsless of the said settings. 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.

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).

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.

Best regards,

[freenet-support] Which indicator determines general freenet performance? CPU bottleneck or not?

2014-07-05 Thread Wolfram Goetz
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.

Best regards,

Wolfram

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.

[freenet-support] 3TiB-Node: Installation fails with Java out of memory error

2014-04-14 Thread Wolfram Goetz
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.
Restarting JVM.
INFO   | jvm 1| 2014/04/14 17:08:17 | WrapperManager Error:
java.lang.OutOfMemoryError: Java heap space
STATUS | wrapper  | 2014/04/14 17:08:17 | Filter trigger matched.
Restarting JVM.

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?

Best regards,

Wolfram
