Noticed a huge difference in Garmin G1000 panel response times after a database cleanup

I work at a shop in Wichita that handles mostly Cessnas and a few Beechcrafts. For the longest time we had this 172 with a G1000 that would lag bad when switching pages or inputs, like a solid 3-4 second delay. The owner just lived with it for about a year. Finally had a slow week so I dug into it. Found out the nav database had like 5 cycles of old data just piling up in there, plus a ton of corrupted flight logs. Deleted all the extra cycles and ran a clean format on the MFD card. After that the response was basically instant. Has anyone else seen this kind of improvement just from purging old database files on these systems?

Found the exact same thing on a 182 we had in the shop, old database versions just sitting there making the whole system crawl. Cleaning out the flight logs and old cycles took that lag from a painful 4 seconds down to almost nothing. It is honestly the first thing I check now when someone complains about a slow G1000.

The 4 second lag was exactly what we saw on a 2008 DA40 I worked on last year. Took out three old databases and cleared the flight log archive, the thing ran like new again. I still don't get why Garmin doesn't just auto-purge old cycles after a certain point. It's such a simple fix that saves so much headache. Take this with a grain of salt but I've never had this trick not work on a slow G1000 in the last 5 years.
