I have an older Droid Incredible running Cyanogenmod 7.2. Recently, I've noticed some sluggishness on the phone that doesn't seem limited to a single app. The CPU Usage Plus app (which I think just runs
top) often reports that the
mmcqd\2 process is using up a lot of CPU (sometimes 50-60%). Googling around, it seems that this process is somehow related to SD card access.
Is there any way for me to diagnose in more detail what exactly is causing this process to use so much CPU, e.g., by seeing what other process is accessing the SD card? Could re-formatting the SD card help? Or could CPU Usage Plus be leading me astray? I have some apps installed on the SD card, and I could try moving them all back to the phone, but it would be nice to figure out a more detailed diagnosis before trying random solutions.
