I have an AMD Athlon X2 260 processor (dual core @ 3.2 Ghz - No over clocking, default BIOS values) running on an ASUS motherboard. It is a brand new motherboard and has 4 GB RAM. I have installed 12.04 -64 bit on it. All updates installed
Firstly, it takes about 13 secs to log in and see the desktop wallpaper after entering the password. Beyond that, it takes 3 seconds more to see the Unity Bar and the icons.
Whenever I am opening any application for the first time, it takes anywhere between 10 to 30 seconds. For e.g. Firefox browser (25 secs) , Gwibber (15 secs), Empathy (12 secs), Evolution (27 secs), Home folder (7 secs), Writer (17 secs), Calc (12 secs), Impress (14 secs), Jokosher & Audicity (22 secs), Ubuntu Software Center (26 secs), Filezilla (10 secs), Cheese (11 secs)
It is extremely annoying to wait for the application to open for the first time. Once the application is opened, then probably it remains in the cache and hence, if I close the app and open it again, it opens faster than the blink of an eye.
I have enabled desktop screenlets to check the processor & RAM utilization. The values are quite normal. RAM fluctuates between 15% to 30% depending on how many apps I have opened. (After the PC boots, memory utilization is 386 MB out of 4 GB with no utilization of SWAP space) and processor utilization fluctuates between 2% to 20% with sporadic peaks reaching 65% to 75%.
As and when I start opening apps, memory utilization goes up and if I open all of the above apps, it reaches to about 1.4 GB.
Following is the hardware configuration
AMD Athlon X2 260
ASUS motherboard M2xxxx-LE
4 GB 1333 Mhz RAM
80 GB Seagate SATA HDD for the OS
1TB Seagate x 2 for data storage
Standard USB Keyboard Mouse
Logitech C11 USB Camera
GEForce 7800 PCI Express Display Card - 512 MB Ram
Dell 22" LED and Samsung 20" LED monitors
Ubuntu 12.04 LTS 64 bit
I have a partition where I have Ubuntu 11.10 - 64 bit running. Surprisingly, that installation is working very nicely. Quite decent speed. Everything under 2/3 seconds
Any help to resolve the issue is welcome
