A checklist of things to do (including some already mentioned): * Use "top" to check for CPU usage and watch iowait time. iowait will show up as a percentage.
* Use "top" and "free" to make sure you are not using swap. * Use "iotop" to check active disk users. * Figure out how to use "dstat" to have an updating readout of the above mentioned stats * Ensure that your partitions are not more than 75% full as it encourages filesystem fragmentation * If you have a small filesystem (say less than 100GB) and are regularly creating, destroying and copying around large 1GB+ files and using tools like BitTorrent your filesystem will suffer from fragmentation * Check the output of dmesg for IDE/SCSI related errors. * Use a S.M.A.R.T disk monitoring tool to check for overheating or failing drives. If your hard drive is running out of of reallocatable sectors it will become very slow. * Advanced thought: Did you switch from ext3 to ext4 as part of the upgrade? If so are you using any fsync() heavy apps? The structure of partitioning shouldn't make a difference. In fact having everything in one giant partition helps prevent filesystem fragmentation in some cases. -- Bruce A.
