kali linux runs really very slow and it laggs

Hello,
I installed Kali linux v 1.1.0a /64bit on my PC (HP Pavilion DV 7 with processor i7 2.20GHz
with 8 cores , and 8 GO RAM, 6 Mo Cache , 1 Terra HDD Toshiba) in dual boot with Win8, but I find a problem that kali runs very slowly and laggs , for exemple when I execute command it takes secondes to runs in place of runing directly , and it do some lagging , so can you help me please ?
PS: I did "top" command to see if there is some running programs that works with a high pourcent , but I find nothing the max usage of programs with CPU do not exceed the 8%.

thank you in advance :).

One possible reason is swappiness... You can check swappiness on your machine. Here's a nice article (it's for Ubuntu, but the same principles should apply):
http://askubuntu.com/questions/10391...ure-swappiness

If you don't have a swap partition, you might consider a swap file. You can Google ways to create one...

What did you set swappiness to?
What is the output of "uptime" (just interested in the load average) and "free -m"? Also, what processor does your machine use (what is the output of "cat /proc/cpuinfo")?

What graphics card is installed
the tools in kali are Nvidia CUDA ready

so is there a nvidia or AMD card
or a hibred intel/nvidia chip

seeing as kali is based on Debian
the debian documentation is a MUST READ!!!
fallowed by taking the "offensive security" CLASSES

HOW was kail installed ?
a custom partition set up ?
a LVM set up ?
Or a FULLY ENCRYPTED!!! ( RECOMMENDED!!!! ) install
( with a very long and complex "pass phrase" )

what?

Code:

root@Pentester:~# cat /proc/sys/vm/swappiness

10

There is the outputs of all other commands :

partition is installed normally on a normal partition that takes automatically all free space available on HDD in dual boot with windows8 (I installed it one day without dual boot I mean kali linux on only and the problem of slowness persists)
I did not used a Fully encrypted, It's just installed normally without encryption because i use kali just for pentesting my developped web application .
thank you all for reply.

in addition I used the "time" command to see and this is the result of execution time for sqlmap:

sys 0m0.168s

Well I don't see any problems in your output. Quad core processor (you said 8 in your OP, but it's not, it's only 4) with a load of ~1 means it's only ~25% utilized, so you're not running out of CPU. You have plenty of RAM available and are hardly using any cache, so swappiness isn't an issue either. If you run top while executing a process that's slow to respond, does anything pop up and show heavy CPU usage?

HDDs are notoriously slow as well. Once the data gets cached it shouldn't be too bad, but the first time you run anything it might take a few seconds to fetch all of the necessary data from the drive. I haven't installed an OS on a mechanical HDD in over 5 years because they're so terrible. You could also have a dying drive, what is the output of "smartctl -a" for your system drive?

Concerning th HDDs , you are right about this , but one thing I should say it that the HDD is very new (I bought it since the last month), and this is the output of smartctl command:

Code:

root@Pentester:~# smartctl -a

ERROR: smartctl requires a device name as the final command-line argument.





Use smartctl -h to get a usage summary

thank you in advance

You need to give smartctl a drive. Assuming your system drive is /dev/sda, it would be "smartctl -a /dev/sda". You can get the name of your system drive with the output of "df", see which drive is mounted at /.

Eg:

Code:

$ df -h

Filesystem                Size  Used Avail Use Mounted on

/dev/sda5                  21G  14G  7.6G  64% /

devtmpfs                  7.8G    0  7.8G  0% /dev

tmpfs                    7.8G  110M  7.7G  2% /dev/shm

tmpfs                    7.8G  77M  7.7G  1% /run

tmpfs                    7.8G    0  7.8G  0% /sys/fs/cgroup

/dev/md126p2              912G  701G  203G  78% /home

The /dev/sda5 partition holds my main OS. /dev/sda is the drive that partition lives on.

hello can some one help me please ?

Maybe you could be more specific about what runs slow.

Do ALL commands run slow or just some?

When you run top, does it take many seconds to start up? Free? ps aux? smartctl?

Is it maybe just network or database operations that are slow?

And perhaps quantify just how slow some repeatably slow command is.

this is the output of smartctl command:

I don't see anything particularly troublesome there.

I think it's time for some benchmarks...do you have any programming knowledge?

the Most kali commands and programs runs slowly and it "lags" , for exemple this commands "Free, ps aux, smartctl" runs normally without arguments , but when I use arguments it takes some milliseconds on my PC with i7 processor, but other commands like msfconsole (for exemple) or sqlmap without arguments it take some "seconds" to run , or when I run iceweal browser it takes 2 ou 3 seconds to run , and in progress of working with browser it laggs .
Concerning network it runs normally (I have 8 Mo speed connection) and when I do an apt-get update , it show me connection with lagging display..
