High bandwidth usage

Hi.
I've noticed (using Activity Monitor) that my Macbook is using a large amount of bandwidth downloading what seems to be nothing. I can't figure out what it could be downloading, but no programs are running and it's receiving data from somewhere in the ether at between 50 KB/s and 200 KB/s. I'm concerned as to what this could be, if it is a problem, and how to resolve it, as I am currently connected to a university network (in the halls) and am worried that I'll be disconnected for overusage. It's already clocked up about 1.5GB receiving today.
Also note that it does this randomly for about 20 minutes at a time: it seems to do this then drop to about 2 kb/s download without any programs running.
Anyone have any suggestions as to what is happening?

The issue seemed to be local network traffic.

High bandwidth usage while inactive

Twice today I've glanced at Activity Monitor's Dock icon, which I have set to view Network Usage, and saw a large amount of data streaming continuously through my internet connection.
This morning when I noticed it for the first time, I poked around my system, and after not seeing any other programs (Safari, Software Update, etc.) being active, I tried quitting Messages Beta - and the bandwidth instantly dropped down to nothing. At that time, it was moving around 60KB/sec upstream, and probably around half that downstream according to Activity Monitor.
A few minutes ago this evening, I saw it happen again - my Activity Monitor was showing heavy continuous bandwidth usage. This time I simply set my status to 'Offline' in Messages Beta and once again it instantly dropped down to nothing. This time the bandwidth was closer to 160kb/sec upstream, and half that downstream! When I changed my status back to 'Available' a few seconds later, everything continued on normally, with almost no data usage.
I had no active chats going, never used video, screen or file sharing - so what in the world is Messages Beta doing with so much data streaming? I'm quite mystified, and wondering if anybody else has seen this happen....

The issue seemed to be local network traffic.

WRT160N Bandwidth usage

Does this router monitor or meter bandwidth usage? Using Vista Home Premium OS, two other computers with WMP54GS and WMP54G PCI adapters and a PSP.
Can it be configured to monitor or meter usage? Can I see the actual usage in real time?
Question 2: (I can ask this elsewhere if you want) Is there a way to extend the antenna on WRT54G & S adapters since they tend to become shielded by the computer case itself?
Thanks

No Linksys router do not monitor band width.nor they can be coinfigured to do so. You can use high gain antennas for the adapters.

What is the actual bandwidth usage?

When I use Adobe Connect I am online and broadcasting for about 4 hours a day, for 10 days at a time. I only do screen sharing and voice -- no video.
I have DSL Internet. The DSL upload speeds are very poor (under 1Mb). To speed things up, I thought I'd look into getting a 4G hotspot, but I'm worried about actual bandwidth usage, since such plans have a practical limit of 5 or 10Gb per month.
My off-hand guess is that If I were to watch a video of myself, I guess it would be a couple of gigs for a four hour, non-HD video. So by that very rough guestimate, I'd hit 20Gb pretty easily over the 40 hours of my meeting. Is that right the way to think about it?
Has anyone monitored actual consumed bandwidth for a simple meeting of one person talking and sharing his screen? I'm not looking for definitive answers -- just some ballpark estimate of what such a meeting consumes each hour...
Thanks! :-)

FF resolution settings to lower bandwidth usage

Which versions of FF will do this and what specific settings are there to lower bandwidth usage?
Also, will the FF settings override settings on websites such as youtube? For example, if my kids were to click on higher resolution or HD video settings for their youtube videos, what would happen?

Changing the resolution doesn't have any effect on the Firefox performance and may even look worse if you operate an LDC monitor not in its native resolution.
You can block content if you ant to improve performance on a low bandwidth connection.
You can look at Adblock Plus.

What Is The Network Bandwidth Usage Report?

I'm looking at the "Network Bandwidth Usage" report and it's just a list of devices with no bandwidth numbers? Is it ordered by amount of usage and if so, why isn't the usage displayed in the report and how do I see the usage for a device?

Optimize network bandwidth usage in large multi-size corporate environments

SymptomsTo maintain a high protection level, you may notice an increase in bandwidth due to the increased number of updates released per day. Policy Manager Proxy (PMP) installations are especially affected as the additional strain on the likely slower network connection that exists between the remote site hosting the PMP installation(s) and the main corporate site with Policy Manager Server (PMS). The network bandwidth usage can be especially high when computers are turn on on Monday as the update packages accumulate over the weekend.
DiagnosisBy default, the Automatic Update Server (AUS) in PMS calculates byte-level differences for the last five update packages (per update channel). In the event where computers were turned off over the weekend, client machine has missed five updates, and PMS will then download a full update package (Aquarius Windows updates can be approximately 140MB in size). When this happens, network bandwidth usage can be excessively high.
SolutionWe recommend applying the suggested changes on all PMS and PMP systems and all of the F-Secure clients behind PMP installations. This may reduce the update size from 140MB to 10MB. The suggested solution consists of three different changes, outlined below:
1. Increase the number of byte-level difference files stored by the PMS
For Windows
To increase the number of byte-level differentials maintained by Automatic Update Server:
Open [F-Secure Installation Path]\FSAUS.PM\conf\server.cfg in Notepad.
Find the key num_old_versions_to_compare, change the value to 50, and save the file.
Restart Automatic Update Agent (AUA) and Automatic Update Server (AUS). In command prompt: net stop fsaua, net start fsaua, net stop fsms, net start fsms.
For Linux
To increase the number of byte-level differentials maintained by Automatic Update Server:
Open /etc/opt/f-secure/fsaus/conf/server.cfg.
Find the key num_old_versions_to_compare, change the value to 50, and save the file.
Restart Automatic Update Agent (AUA) and Automatic Update Server (AUS) daemons (root privileges required): #/etc/init.d/fspms restart
The overall disk space requirement for PMS increases. We estimate the disk consumption to increase by 10GB. Make sure the hard disk hosting the Policy Manager Server installation (Program files\F-Secure\Management Server 5\) has enough disk space.
2. Increase the cache size available on the PMP for storing files
For Windows
Note: Use the Advanced mode in Policy Manager Console (View >> Advanced mode) to edit the setting.
Go to F-Secure Policy Manager Proxy > Settings > Communication > Cache size.
The default setting is 500. Increase this to 5000 (5GB) and distribute new policies.
Verify the setting on all Policy Manager Proxy systems and adjust the settings, if needed. The setting specifies how much disk space is set aside for storing databases on the Policy Manager Proxy.
For Linux
As Policy Manager Proxy on Linux is not centrally managed, the change involves modifying a configuration file that exists on the Policy Manager Proxy system locally.
Open /etc/opt/f-secure/fspmp/conf/proxy.cfg.
Find the key max_cache_size, and change the value to 5000: max_cache_size=5000.
Restart the fspmp daemon (root privileges required): #/etc/init.d/fspmp restart
3. Adjust the F-Secure Anti-Virus client configuration using Policy Manager Console (PMC) to help prevent clients from immediately falling back to downloading updates directly from the PMS.
In case the client is unable to connect to the Policy Manager Proxy, for example due to high network traffic and multiple downloads taking place, the following setting dictates how soon the client attempts to connect directly to the Policy Manager Server to download updates.
In Policy Manager Console, go to F-secure Automatic Update Agent > Settings > Communications > Policy Manager Proxies > PMP Proxy fallback time.
Default value is zero which means fallback to PMS takes place immediately, in case where Policy Manager Proxy installation cannot be reached. To prevent this from happening, configure this setting to a higher value (suggest 7 hours).
These steps should ensure database updates are only downloaded via the PMP.

Excessive bandwidth usage

My wife's school has been using SGD for for a couple of years to allow her to remote desktop to her school PC from our home one - using just Word and Excel. In the last couple of months SGD has gone from using a few hundred MB per day to ~5-8GB per day - that is more than we used to use in a month! Does anyone know why this may have occurred?
Is there anything that can be done to reduce it?
Needless to say our ISP is very happy to charge us extra for all the extra bandwidth we now need. Nothing has changed at our end.

Hi.
Do you know which SSGD release has been installed on the server (at school I mean)?
You could simply ask an SSGD administrator to type "/opt/tarantella/bin/tarantella version" to find it out.
That's rather strange since SSGD is highly optimized as to reduce the network traffic.
Are you sure it's SSGD which is causing that huge bandwidth usage?
Give a network monitor/sniffer (eg, http://netlimiter.com/download.php) a try so see if there's something else which is hogging your bandwidth.
Cheers,
Rob

Config Manager Agent - after Hardware Inventory High CPU Usage with WMIPRSVE and very fast empty Battery

Hi there,
since a few days there is on some machines (40-60) a high cpu usage on one core (quad core cpu machines) with the WMIPRSVE.EXE if the HARDWARE INVENTORY CYCLE started.
i try out some tests, read some forum articles and troubleshooting the WMI management but a real problem i doesn´t see.
in some articles i read that hardware inventory runs about minutes up to more hours but some machines runs longer, someone more as 1 day.
here an example of mine PC:
at 8:07 i started Hardware Inventory Cycle, in the InventoryAgent.log i can see that some Collection Namespace are captured.
after a few minutes there stopped and does nothing round about 5.9 hours or better, after 21436.097 Seconds.
For any hints i am grateful. :)

Looks like something in one or both of those wmi queries. it goes from 8:10:03 to 14:06:43 right around there. 6 hours to do that...
try running those queries from wbemtest manually; and see which one just never finishes.

Very high memory usage..possible memory leak? Solaris 10 8/07 x64

Hi,
I noticed yesterday that my machine was becoming increasingly slow, where once it was pretty snappy. It's a Compaq SR5250NX with 1GB of RAM. Upon checking vmstat, I noticed that the "Free" column was ~191MB. Now, the only applications I had open were FireFox 2.0.11, GAIM, and StarOffice. I closed all of them, and the number reported in the "Free" column became approximately 195MB. "Pagefile" was about 5.5x that size. There were no other applications running and it's a single user machine, so I was the only one logged in. System uptime: 9 days.
I logged out, logged back in, to see if that had an affect. It did not. Rebooted and obviously, that fixed it. Now with only FireFox, GAIM, and a terminal open, vmstat reports "Free" as ~450MB. I've noticed if I run vmstat every few seconds, the "Free" total keeps going down. Example:
unknown% vmstat
kthr      memory            page            disk          faults      cpu
r b w   swap free re mf pi po fr de sr cd s0 s1 s2   in   sy   cs us sy id

In any event, we can see that FireFox is sucking up 145MB (??!?!!? crazy...) XSun, 200MB, and java 190MB. I'm running Java Desktop System (Release 3) so I assume that is what accounts for the the high memory usage RE: java process. But, XSun, 200MB?
Is this normal and I just need to toss another gig in, or what?
Thanks

Norton reports high memory usage with firefox and it crashes often

Norton antivirus 2011 has pop up warnings reporting high memory usage from Firefox. I have been getting theem often and my computer is crashing often after those pop up warnings. Thanks

Safe mode did not help.
I have disabled ALL extensions and plug-ins, but the problem with "zig-zag" memory usage still remains (I've not tried to leave browser open for the night yet).
I think I'll do clean reinstall with completely new empty profile (without sync'ed information) to try this out. If this works, I'll start adding stuff (configuration, sync, features, etc) to see what causes the problem.

SA520W - High memory usage, possible fix in 2.2.0 firmware?

As suggested by Thomas Watts, I'm starting a new thread to discuss the new SA520W firmware (2.2.0) and a possible resolution to high memory usage I'm experiencing on my network.
My current setup is: 16Mbit DSL > SA520W > SA300-10, all with stock settings (no fancy VLAN's etc.)
I have 4 CentOS 5/6 servers and a Windows 7 Ultimate station connected to the switch. I use CIFS to connect from Windows station to the other Linux servers and send large files. I currently notice the following behavior:
When the file transfer starts, the Intel 1Gbit NIC is nearly saturated, hitting 115MB/sec. After few seconds, the data transfer comes to a halt and the transfer speed drops to around 50MB/sec. If I check the memory usage before the file transfer, it is approximately to 50-60% (on a fresh router reboot). Every time I send large files to other machines, the router memory consumption increases and it does not lower after a reasonable delay. I end-up with high memory near 90% and the only solution I have is to reboot the router in order to bring it back to 50%.
Now, Thomas told me that this is simply a cosmetic issue, the memory is not actually 90% used. Yet, when the memory hits this threshold, I'm not capable to send files are normal LAN speeds I'm used to. Rebooting the router allows me to send only ONCE (and for few seconds) data at the expected LAN speeds.
I would apreciate any input from Cisco engineers as well other users who experience the same issue. I would also like to know if any related work was done into 2.2.0 firmware and when we expect to have it released to users.

Floren Munteanu

Hi Tom,
See below the answers.
Are you currently running the 2.1.71 code?
Yes
Are you using IPS?
No, the LAN is for internal use (no external users allowed)
Are you using Protectlink services?
No
Hardware wise, I did not changed anything on machines. All boxes have dual Intel EXPI9301CT NIC's (LACP was planned) but I currently use single connections for sanity reasons (disks won't allow greater speeds anyway). Previous to Cisco, I used a Netgear ProSafe router + switch which did not encountered the issues I mention. Honestly, at first I thought I'm dealing with some stupid disk issues on Windows. So I ran a quick test and the stats are proper:

As I mentioned before, everything is pretty much stock on router/switch settings. If you have any tips that allow me to identify the cause, I would appreciate the input. What puzzles me is the speed drop and quick memory usage increase. It occurs 7-10 seconds after the transfers begins. It looks like the data transfer hangs for a very short period of time (less than half of second) and the transfer speed decreases from 110-115MB/sec to 50-60MB/sec. The transfer is completed at this speed. No matter how many other files I try to transfer after, the speed won't go higher than 60MB/sec. If I reboot the router, I get the same cycle.

Google Earth Plugin and LabVIEW: High CPU usage when adding placemarks

Hi,
I posted this question on stackoverflow earlier this week but feel it might be better suited to the LabVIEW community specifically so I'm reposting here:
I'm writing an application which uses the Google Earth Plugin to display events on the globe. Each event is a single point kml placemark with an icon which is a 3kb png file. Placemarks are uploaded to the plugin as they are received by the software. I am experiencing increasing CPU usage with the number of placemarks that are added.
I have tested displaying a new placemark every second and running until the software running the plugin completely froze (graph attached). The GEPlugin (green trace) stopped responding (i.e. the globe did not respond to the mouse) at around 1200 placemarks added and CPU usage was at ~30%. When the software itself (red trace) froze the plugin was using around 50% CPU and ~3700 placemarks had been added). After the freeze, no new placemarks were added which caused the software to respond (but not the plugin) so I could clear all the placemarks. After the placemarks were cleared from the globe, the CPU usage of the plugin returned to around 5% CPU.
So what I've seen is that GEPlugin CPU usage increases linearly with each kml placemark added. Is this the expected behaviour/ a normal limitation of the plugin? If not is there a more efficient way of adding many placemarks to the globe?
I am using GEPlugin version 7.1.1.1580 (API version 1.010) and LabVIEW 12.0f3
Please see the test results attached. Any input greatly appreciated!

Hello,
I have had a look at your graphs and understood what you are trying to do. To me it seems that as the image gets more complex it gets harde to render which wold likely cause increase in CPU usage resulting in the freeze. I would suggest you try running the program on anoher computer to check on the RAM front of things. If this is a limitation of the GE Plugin then unfortunately I can not do much to help, but if you think this is a problem coming from your LabVIEW code then you can post your code here and I can take a look.

Firefox becomes really slow then eventually unresponsive when loading a page with many hires images. Unsual high memory usage up to 2gigs just for firefox. Was never a problem with v3.6.

When loading a page with many hires images, Firefox becomes really slow and scrolling becomes jumpy then eventually becomes completely unresponsive. Unusual high memory usage of up to 2gigs just for firefox when loading these pages. This was never a problem with v3.6.

I encountered the same type of problem. Firefox running terribly slowly and slowing down my entire machine (Core i5 with 256GB SSD). Searching the forums, I found a couple of things about troubleshooting performance issues, one of which was to use '''hardware acceleration''', that is on by default. It was turned on on my PC, '''so I tried deactivating it, and it worked!'''
So doing the exact opposite as Mozilla support said solved the problem. It is really a pain now to work with Firefox. I'm using it because I have no choice, but I'd recommend IE and Chrome over Firefox... Whatever, the market will decide once Firefox has become to crappy...

High disk usage/high memory usage.

i keep getting high memory usage and high disk usage in ps cs6.
its slow when i open a file. how can i solve this problem.
thank you.
philip.

Not to put too fine a point on it, but more than what? More RAM is almost always better, but you haven't answered most of the questions posed here. The answer might be different if you have 2 GB of RAM or 32 GB of RAM already. A 9 megapixel document could get rather large with a lot of layers, but again you've neglected to give any hard info about its size.
Regarding your video card, that's a bit of a judgment call you need to make. For Photoshop CS6 I currently advise people to try to get a video card that gets a score of 1000 or better on this benchmark: http://www.videocardbenchmark.net/high_end_gpus.html
Video card speed will matter when you're editing those 3D components and video card VRAM will also matter, but possibly even more importantly your GeForce 320 is a bit old, and nVidia may just not be doing their best driver work for it any more.
Everything in general will run more smoothly with a powerful modern video card. I like to recommend a VisionTek ATI Radeon HD 7750 - or if the computer power supply and your budget allow, the even more powerful 7850. VisionTek does a very good job with their hardware, IMO, and it comes with a lifetime guarantee.
Keep in mind that if you switch from nVidia to ATI or vice versa, you should carefully sweep your system to ensure all files from the old card are removed, then visit the web site of the new card's maker and download/install their latest display driver release.
Best of luck.
