Current Behavior

util upload-state CLI command utilizes MPT-backed storage (in particular, Seek operation over the whole contract storage). As it is postulated in https://github.com/nspcc-dev/neo-go/pull/3845#issuecomment-2756597644, the Seek&upload time at the same blockchain height varies from 26-30min to 1h25m. 26-30m is an expected value that is comparable with the full MPT traversal process, but 1h25m is something unexpectedly slow.

Expected Behavior

At least, I'd expect Seek operation to take relatively the same amount of time for the same blockchain height. It would also be nice to optimize traversal time, but I'm not sure we can do it.

Before digging into this issue we need to try to reproduce it in "aseptic" environment, i.e. to measure a pure Seek time at 7M of mainnet height without any additional overhead brought from objects uploading or dump file construction.
