I have the following system configuration for my PC:
(1) CPU - AMD FX 6100
(2) Motherboard - Gigabyte GA-78LMT-USB3
(3) RAM - Kingston 4 GB DDR3 at 667 MHz
(4) GPU - AMD Radeon HD 6450 1 GB DDR3 Sapphire Edition
(5) HDD - Seagate 160 GB at 7200 rpm
(6) DVD Drive - Asus DVD RW Burner

I am currently running Windows 7 Ultimate (64 Bit) alongside Ubuntu 13.10 (64 Bit). Why Ubuntu is running slow than Windows 7?

1. How are you measuring the speed of Windows and Linux?

2. Do all applications run slower or is it a particular class?

3. What performance monitoring have you done? For example, have you used "top" to examine running processes (or I'm sure there is a GUI environment for those who can't type).

Normally everything seems to be same in speed or performance of Ubuntu along with Windows 7. The only exception is the start time of Ubuntu, which is taklng too long from that of Windows 7.
You can say, Windows 7 loads with everything in about 15 seconds after the welcome screen, but Ubuntu is starting about 20 seconds after I log in with Ubuntu password. Normally I have seen Ubuntu starting almost instantly or merely a few seconds of gap after log in but I think this is exceptionally slow for Ubuntu as far as start time is concerned.
Is this happening because I am running dual operating systems?

Check your "dmesg" output for obvious flags as to why there is a time lag.

You can also install packages "bootchart" and "pybootchartgui" and upload the .png file in /var/log/bootchart.
This will graphically show what is taking longer.

Also also check "/etc/fstab" for erroneous entries like a floppy drive or drives that do not exist. (listed as something like fd0). If found simply comment them out.

20 seconds to load Ubuntu doesn't seem unusual and is really not worth worrying about. If you really want to cut down load time a custom kernel would help.
