Hello, My Surface got kind of slow after applying and then unapplying BitLocker. I turned the feature on several months ago and didn't notice much of a performance difference other than a bit of lag upon waking from hibernation. However, about a month ago I decided to install Ubuntu on a 10 gig partition; I wasn't able to do so until disabling BitLocker. Ever since I turned it off, the hard drive access time has gone through the roof. It can take 10-15 seconds to wake up from hibernate and 5-10 seconds to display the contents of some folders (Downloads seems to be a particularly common culprit even though I only have ~15 small files there). I'd like to improve performance back to its original level; ordinarily I'd do a defrag but I'm not sure what my options are with an SSD; from what I've read the "optimize" feature is already enabled and runs periodically. What can I try to speed up the SSD? Thanks!
