Why My Linux Is Slow?

Hi there. I need to slow execution of certain portions of my programs (GFortran) to demonstrate in "slow motion" interpolation between points on a graph. The SLEEP subroutine requires a default integer as an argument and thus appears to be too slow. I found one subroutine but it eats up 100% of CPU time. Thanks, - Alex

My command linux text console=ttys0, 115200n8 is not working. What is wrong with this command? Please help me.

Hi

I'm a telecom/IT contractor and my work laptop died so instead of buying a new one, I decided to give my spare laptop a try. It's a cheap Lenovo G585 with only 2Gb ram and a AMD E1. Needless to say this is a real slow laptop. W8 was preinstalled and barely runs. Even for simple work related tasks its too slow.

Instead of wasting money on it, I am contemplating the idea of installing a Linux distro. I manage via ssh a few linux servers for my customers (centos, red hat, ubuntu server) but actually never used it as my main OS.

I just want something lighter than W8 so the laptop will be faster. Which distro should I get? I was thinking about LXLE but there's too much distros I can't choose.

Speed is the priority in this case. I also like a good looking UI.

Also, how's Microsoft Remote desktop from a Linux client? Is it fast and well optimized?

Thanks!

Hello all, before I get started I just want to make it clear that I have done hours of research on the question I'm about to ask, so... lol

Anyway, I am completely-totaly new to linux, of all forms, have been a Windows XP Pro guy for years now, and it's what I know inside and out.

Well that's beat, even though I still am using it, and I can't afford a new pc or a new windows cd. I'm broke for now. Besides all that, I like linux so far from what I ahve been woking with. (xubuntu)

[QUESTIONS]:

I bought a notebook from a very desperate crackhead for $20:

Compaq Presario x1000
(not much ram, i think only 256 or 512)
-It's slow as #$@%, but I managed to install Xubuntu on it, and it still sucks. Very. Very slow. I cant watch any videos on it or really do anything other than just look up websites, and that sucks too.

Sorry, nevermind that above, I am just stating that so you see what my first Linux introduction has been. This is what I have got used to so far, and I seem to like it.

I am not at all concerned with this notebook at this point. However, what I am concerned with, and this is my main question:

I have a Desktop:

P4 2.6 GHz /1.5 GB Ram
- I have XP Pro SP3 installed on the 1st partition and I installed Ubuntu v14.xxx (very latest version) on the 2nd partition.

It's extremely slow, but XP runs just fine. I chose the first option upon install where it does the auto-setup running alongside XP.

So far I do not really like it. I have no start menu like I had on the notebook in the upper left hand corner, and I kind of like that.

Well through messing around I'm guessing that is something called: xfce ? Not sure.

Anyway, sorry for rambling about, but here is my MAIN QUESTION:

What Distro of Linux should I install on this PC where it will run nice and fast/smooth?

~thankyou.

Hello, My issue is very common but, not able to resolve it.

Issue I am facing with my Linux (RHEL-5 32-bit) machine, where I am not able to connect to internet.

DWR-113 - D-Link Router is configured for 3G dongle (Vodafone India) - This setup is done via WiFi and not using the provided LAN cable from Win7 machine.

Internet is working absolutely fine in case of Wireless but, at same time when LAN cable is used internet is not working. [Able to ping to Router IP i.e. 192.168.0.1)

Similarly, from Linux box, ping to Router IP is working [LAN plugged] but, Internet not working. IP of linux machine: 192.168.0.60

Also, able to get the console connection of Linux from Windows box..[Windows connected to Router via WiFi and Linux connected to Router via LAN cable]

Please suggest how to get rid of this problem so that Internet will work on Linux via LAN cable.

Many Thanks,

I have Windows 8.1 Update as my HOST operating system.
I have installed vmware workstation and installed on it the latest
version of CentOS (7.0) as Guest OS.

I have 8 GIG of RAM and have allocated to VmWare around 5GIG~.
HDD size is 30 GIG.
I also have de-fragmented the HDD.

From the beginning of the installation of the CentOS it was SLOW. It is NOT a sudden change or decline in performance.

Formerly, I had installd CentOS 6.4 which worked OK and had not speed problem while I just had allocated 1 GIG of RAM. Where do you think lies the problem?

Hi Everyone,

We are using Dell Power Edge R510 server as a central storage in Linux network. I have configured RAID6 on 10 near-line SAS hard disks. Using NFS i have exported one directory and mounted it on other machines.

Recently we are facing one problem, when anyone read/write big file (2-3GB)from NFS drive,others feel very slow access to that drive. Sometime we can't open simple text file till complete read/write process.

I have remounted NFS drive but still problem as it is.

Can anyone help me to solve this problem.

Hi,

I am currently working on a Embedded system (linux 2.6.24) and need to set a ftp daemon on it.
I have the busybox v1.4.2 on it but it don't have ftpd on it.
After searching on internet i find tons of way to install a ftp daemon on normal linux computer but no explanation on how to do it on an Embedded devive.
I am not the one who installed the distro and busybox, i have no knowledge on how to make this. I have no sudo/apt-get/make command on my system.

Hi friends ,
i am new to linux , i have a script , to auto start/stop a application whenever linux reboot.
