I have feeling recently of lately with the PC speed. There may be a problem of internet connection speed, however, CPU sometimes does not work or occupied by some software e.g. chrome, mcshield.exe etc. I am afraid that some software does harm in my PC. I feel the lately especially when I connect to the Internet. I have tried no image, no cookies settings, however, did not work well.
I have checked some information on this matter in Japanese :). Late reading of web pages @ Goocle Chrome Official Help Forum http://www.google.com/support/forum/p/chrome/thread?tid=4371d1c674b5772a&hl=ja DNS prefetch function setting could improve the late speed in this case, however, it did not work for my PC.
Data transfer speed of Flash is late with Google Chrome http://xxsionxx.blog17.fc2.com/blog-entry-1314.html Data transfer speed of Flash was compared by browser software. This may not be relevant for my PC.
3. Problems in browser software. There may be problems in my PC (#2), not so bland new, however, it worked well a few weeks before, therefore, I think, enough for some standards, CPU, memory and so on. I am afraid about decreasing of the amount of space in HDD. I will try to check this problem later.
