For me a change to SSD helped a lot as disk i/o on updates are a lot. Takes a long time for that and search indexing.
I also turned off this:
It's not only my internet but disk I/O that takes a pummeling.
Many times my disk utilization reaches 100%
- how this number is calculated
- how to fix it
Not sure how to add pictures to this post but today at certain time my disk utilization was at 12% and there were 7 process using altogether 1.9MB/s. Later disk utilization was at 100% - 12 processes using 1.4MB/s. So it looks like 100% is 1.4MB/s and 12% is 1.9 MB/s?
