Resurrecting this thread deliberately ....
I have a new build with an SSD for the OS and had been very pleased with the results .... it was booting to LXDE desktop in less than 10 secs (usually about 8 secs I believe).
This machine has been used only for general browsing and email with Firefox, by a family member.
Today I checked it for updates etc and rebooted to be sure all was ok before leaving it ..... only to discover that it is now taking about 40 secs to get to a usable desktop!
I tried the same things as are listed in previous posts, and after issuing multiple 'sync' commands, the residue of the testfile is still reported .... not as expected all zeros.
Details of the build and a video showing the boot are herehttp://www.pclinuxos.com/forum/index.php/topic,109221.msg939996.html#msg939996
So, in the last week it has gone slow .... and I think it happened suddenly ... if so then it might be some hardware problem.
I am considering a complete reinstall to eliminate everything in the OS that just might have become corrupted.
If anyone has any suggestions I would be grateful.
