Entire system slower when Torrent running. Is this normal?

I have what I think is a well-powered Mac with plenty of processing power but I've noticed that whenever I have a torrent program running that my entire system slows down...every program including non-internet related. As soon as I hit "quit" on the torrent program the entire system picks up speed again.
I tried using "activity monitor" to check it out but I didn't see anything that looked incredibly lopsided to me in terms of memory usage. I don't know exactly what I'm looking for though in terms of metrics.
I tried checking the preferences for my particular program (utorrent) and I didn't see particular limitation on CPU usage. Still, I would have thought my system could have handled it.
Is this normal? Is there some other setting I should check out?
Thanks.

This is exactly what you should expect with torrents. Your Mac is acting as a server for strangers when you run torrent software, so of course it's going to run slower. For this and other reasons, torrent software isn't a very good idea, IMHO.

My performance is very slow when I run graphs. How do I increase the speed at which I can do other things while the data is being updated and displayed on the graphs?

I am doing an an aquisition and displaying the data on graphs. When I run the program it is slow. I think because I have the number of scans to read associated with my scan rate. It takes the number of seconds I want to display on the chart times the scan rate and feeds that into the number of samples to read at a time from the AI read. The problem is that it stalls until the data points are aquired and displayed so I cannot click or change values on the front panel until the updates occur on the graph. What can I do to be able to help this?

Entire system crashes when fire fox is run for a short period of time

So I've been building a new PC over the last 3 months and today it's finally complete. When I run Firefox for a short period of time (shortest so far is 10 seconds, longest is roughly 30 minutes) my entire system will just freeze up. Display stays on but nothing I do will update the display and I will need to forcefully shut down the entire PC.
I would rather not switch to a different browser.
I'm certain this only happens with Firefox because it does not happen with IE, and I've been using Chrome for the last 10 mins without an issue. It does not seem to crash is safe mode.
Not sure if I was getting unlucky but I was using the British version of fire fox and it would seem to crash more constantly then the American one.
*EDIT*
I just got the same crash with chrome. But it took a lot longer to happen compared to Firefox. I'm really confused as to what's happening now, I'm going to close my browsers all together now and try doing something else for a few hours, I don't think it's because my system is getting over powered because my stuff is very high end.
I will post my system specs, then leave and come back in a few hours, to check for replies. Sorry if I take a while to get back to you.
If you need additional information just ask.
Specs
Processor-i7 3930k
Mobo-asus p9x79 extreme
Graphics card-amd 7970
RAM-g.skill 16gb 1600mhz
I think that's the necessary specs.
I'll see you all in a while.

Why is my Macbook Pro so slow when I run VM Ware Fusion?

My Macbook Pro is very slow when doing normal tasks (Mail especially) and slows to a stop when trying to run VM Ware Fusion. I need to run this to run a work program and that is the only thing that I do with Fusion. Everything seems to come to a halt when I boot up Fusion and I need to figure out what is causing it.

You do not have adequate ram to run a virtual machine as indicated by your Page-outs. You may also be assigning more memory to the VM guest than is prudent, or number of CPUs it uses. You should also use the latest VMware version available for Mavericks.
The other issue is that your machine is polluted with wireless modem and devguru kernel extensions that may no longer be compatible with Mavericks and may be posing conflicts between each other. Eliminate your login items from within System Preferences > Users & Groups. Launch what you need, when you need it, from the Dock, or /Applications.
Do you use all of those Internet Plug-ins in Safari, or could you remove some third-party plug-ins?

White screen when charging. Is this normal?

I just purchased the 8gb itouch (2nd gen). So far I love it. However, something that seems odd happend twice in the first night that I have had it. With the itouch turned off yet connected to the computer, after a short while I look over at it and the entire screen has gone from "off" to all white even though it is turned off. I turn the device on then off and everything works as it should. Is this just something it does when connected to the computer or should I be exchanging this for a new one at Best Buy?

I'm having the same problem with the white screen on my 32 gb Touch. I connect it to my Mac Book Pro at night look at it in the morning and the screen is completely white. I have to hold down the center button and the top button to get it to restart and when it does the battery is in the red. I've exchanged it twice since September. I sent the last one to Apple and just got a cheery email from them telling me that they can't find anything wrong with it and they're sending it back with notes on troubleshooting.
I absolutely hate it when they pretend that this is the first time they've heard of such a thing. But I have AppleCare and I'm just going to keep taking it back until I get satisfaction.

Macbook air locked out when password changed. is this normal???

My friend had a macbook air running os x lion. When he changed his password ( while we were air dropping a file ) He decided to lock the mac to see if the password change worked. When he typed in the password the mac would not let him in. He had also put a hint on and there was no hint. He had to restart his mac so that he could login.
So my question is....
Is this normal to have this happen because i have a macbook pro and it dose not do that
Thanks everyone
Matt

I can see it, and I know what you mean.
It is normal, for the reason that Retired Engineer gave in his post. Don't be surprised if after a couple of cycles, the capacity rises to 100%, or near to it. It will go up and down, but slightly more down after a dozen cycles or so. It is completely normal to vary like this.

Shape outlines change size when skewed. Is this normal?

Good Morning InDeisgn Experts and Gurus,
I created a shape in InDesign CS5, and applied and outline to it of 4px. However, when I skewed the shape, the size of the outline changed on the sides.
Is this normal? How would I remedy this, besides creating another but slughtly larger shape? See attached image.
Thanks.

I never noticed this before, but it seems the shear tool applies a live transformation at the original object -- you can see the shear angle in the control panel, and change it to something else, or even set it back to 0 to get its previous shape. Apparently, its outline is sheared along with it.
I know of only one way to force the transformation to "reset" to nothing: draw a very small rectangle right on top of your red object. Give it the same fill-and-stroke as the red object (use the Eyedropper tool for this). Select both, and then select Add in the Pathfinder panel. You will see that (1) the shear value in the control panel disappears, and is reset to 0°; and (2), the outline will behave normally.

WRT54GS V6.0 Slow with Torrents running

Hello,
Current Config: WRT54GS - V6.0 - Firmware Version: v1.52.0 (just updated)
WAN info:
All Manually assigned.
LAN - 1 static IP and 1 laptop on dhcp
Issue:
Normal surfing and downloading is perfect, no issues on a 6MB WAN link. The only issue is when I start up a uTorrent program, then all pings and internet access either drops or goes very slow.
The load on the link is less then 1MB - so there is no issue with the torrent system hanging the link.
I believe the router is not closing open connections, or just is not able to handle the Torrent traffic AT ALL.
Troubleshooting done so far:
==> Upgraded to latest firmware (this HELPED, but did not solve issue - less ping drops with new firmware)
==> Tried torrents again WITHOUT ANY ROUTER, this worked pefect!!
==> Tried torrent on different port, same issue.
==> Tried torrent on both machines, no change (only I need to change the port rules on the router).
I do not think this is port forwarding related as I've the correct ports assigned to the torrent machine.
The issue only happens whilest any torrent program is open, it does not even need to be downloading or uploading!
I see a lot of related discussions on this issue on many web sites, but no one has offered an official solution. This is what I'm now requesting.
Router is less then 24hrs old, so I have the option to return it.
Many Thanks,
Joe Leavy

Just use DDWRT firmware and all of your issues with the WRT54G and WRT54GS will disappear.
My WRT54GS used to crash every 2 hours to 24 hours, having to Power cycle it every time. It will just loose connection to the internet and dropping Wireless connection. My WRTG4GS was upgraded to DDWRT third party firmware and has never dropped any connection since.

Firefox freezes entire system then everything resumes running again

As above.Started occurring since v20 came out.Seems like many people have this error.
Reverted to v19.Problems occurs as well.
Tried everything ( starting FF in safe mode , creating a new profile, resetting FF, uninstalling and a fresh install, booting in safe mode Windows). Nothing seems to work.
It freezes again and again only to resume normal service only to freeze again. On and on and on. Really frustrating.
Can someone point to me if this FF's problem or is there a problem with my system itself?
My system doesn't seem to freeze when FF isn't running though.

I've been having the same issues as others. It runs up high % of CPU, a couple GIGS of RAM, and oddly, it runs up my "Inactive memory", two or three times what any other browser does, up to almost 4 GIGS! So it runs down my total RAM availability, as well. It runs slow, freezes, even will freeze when I simply try closing it, requiring a force quit, then when I re-open it LOSES all my previous session, so I have to hunt all over the place to try and manually, laboriously reconstruct it, because for some odd, very frustrating reason, it doesn't show all the pages in HISTORY, when it does work, and open them, unlike every other browser, which makes zero sense to me.
I am obviously very unhappy & frustrated with the totally lousy performance of version 22, and will end up having to use Chrome or Safari....

System hanging when it runs out of memory

Hello,
my system has a finite amount of RAM and swap (it doesn't matter, to my purpose, if it's 16GB or 128MB, I'm not interested in increasing it anyway).
Sometimes my apps completely use all the available memory. I would expect that in these cases the kernel kills some apps to keep working correctly. The OOM Killer exists just for this, doesn't it?
What happens, instead, is that the system hangs. Even the mouse stops working. Sometimes it manages to get back to life in a few seconds/minutes, other times hours pass by and nothing changes.
I don't want to add more memory, I just want that the kernel kills some application when it's running out of memory.
Why isn't this happening?
Right now I'm writing a bash script that will kill the most memory-hungry process when available memory gets below 10%, because I'm sick of freezing my machine.
But why do I have to do this? Why do I need an user space tool polling memory usage and sentencing applications according to a cheap policy? What the hell is wrong with my OOM Killer, why isn't it doing is job?!

Alright, you won, now quit pointing out my ignorance
Your awkish oom killer is a lot cooler than mine, switching to it, thanks!
I did some testing (initially just to test the oom killing script) and found out that if a program tries to allocate all the memory it can, it gets eventually killed by linux's oom killer. If instead it stops allocating new memory when there are less than 4MB of free memory (or similar values) the OOM won't do anything, and the system will get stuck, like if a forkbomb was running.
That's it, this program with MINSIZE=1 will be killed, while with MINSIZE=4MB will force me to hard reboot:
#include <string.h>
#include <stdlib.h>
#define MINSIZE (1024*1024*4) // 4MB
int main( )
int block = 1024*1024*1024; // 1GB
void *p;
while( 1 ) {
p = malloc( block );
if( p ) {
memset( p, 85, block );
else if( block > MINSIZE ) {
block /= 2;
return 0;
Guess I'd need to go deeper to understand why Linux' oom killer works like that, but I won't (assuming the oom killing script will behave).

Entire system slowed down! Others have issue?

Hey Everyone!
Installed new OSX last night, indexing is finished last night.
Safari barely loads sites, perhaps cache building? Doubtful.
Apps responding very slowly.
Mail wont quit.
iCloud slowing system down?
Processor 2.2 GHz Intel Core i7
Memory 4 GB 1333 MHz DDR3
Graphics Intel HD Graphics 3000 384 MB
15-inch, Late 2011 MacBook Pro
I am very sad that I am in the middle of my workday and my system is not performing at all. I run minimal apps at one time, especially today, and I am about crawling on every action I perform.
Anyone have ideas on what I can do here to improve performance (besides more ram as the Keynote specified my system would work "smarter")
Best,
John Sweet

The above might be an issue.
I have only a few apps running right now. I thought this OSX was going to run well with a 4gb system?

How to avoid system slow when login first time everyday

if login system first time every day, it will be very slow for loading web application.
I think maybe it 's reload cache every night or by a certain perods of time.
how to avoid this situation. or set cache reload a time per week?
Thanks.

Terry,
I would confirm your application pools are set up as suggested in the install documentation. This should resolve your issue.
Thanks,

I get the same error. I speed up the virtual memory system of the operating system.

Flash drives and SD/microsd heats up and slow while transferring files, is this normal?

My new macbook pro heats up my flash drives/sdhc/microsd while transferring files. I thought it was just the Micro sd itself (using MicroUSB adapter) but when plugging in a differnt flash drive it too was getting hot and quickly heating up. I also thought it is pretty slow for a Class 10, which i dont think it is the it could be the flash memory, is there something i am doing wrong? its using mac os x journaled format. This also happens when i plug it in the sdxc slot. Any ideas?

I had another apparently hung Time Machine backup today.
Starting Dashboard did NOT fix it this time. However, after what seemed like a long time (probably 5-10 minutes) it apparently freed up on its own and completed the backup normally. This makes it appear my previous result was just "coincidence".
There were a few error messages thrown into the Console this time by the "backupd" process -- An "Error(-43)" while apparently attempting to find a path to a file with a "null" name.
Despite that, the backup seems to have copied what it was supposed to copy.
