If your network slows down or the performance of your Mac inexplicably deteriorates, make sure to have a look in the Console. You might find an error mentioning that a deamon, called Akamai Client, can't find the file loader.pl in /Applications/Akamai. You can find a picture of this error on my blog.
It has been suggested that this problem is caused by any Adobe product, but althought I suspect this to be correct, I can't confirm this. Aforementioned website recommends re-downloading and re-installing the Adobe software and then executing a command line utility, but this didn't work for me. Here's what I did.
I decided to search for the files (in Terminal) related to the problem and typed:
$locate akamai
in the shell. The locate command found two files:
com.akamai.mac.plist
com.akamai.client.plist
One of them was in a deamons folder, the other in a preferences folder. I simply moved both files to the trash and restarted the Mac. This removed the recurring error message from the console window and improved my Mac's performance.
