You probably ran into
[HBASE-6870] - HTable#coprocessorExec always scan the whole table (0.94.8)

Or maybe one of these:

[HBASE-8806] - Row locks are acquired repeatedly in HRegion.doMiniBatchMutation for duplicate
rows. (0.94.10)
[HBASE-8639] - Poor performance of htable#getscanner in multithreaded environment due to DNS.getDefaultHost()
being called in ScannerCallable#prepare() (0.94.9)
[HBASE-9087] - Handlers being blocked during reads (0.94.11)

Eh? That should not be the case, we should figure where 0.95.2 is different from 0.94.
