+#### Description
+
+### What happened?
+
+As mentioned in https://github.com/ikawrakow/ik_llama.cpp/pull/273 I've seen this behavior occur with llama-server (sorry, I never really noted the configurations or models it occurs with), and I can usually mitigate it by canceling and then restarting generation until TG performance goes back to the expected value, the chart below shows this behavior captured in a benchmark.

+
+Also I'm fairly certain I've never encountered this bug in batched-bench only in server and sweep-bench both of which manipulate the KV more than batched-bench.
+
+### Name and Version
+
+Graph capturing this behavior was on https://github.com/ikawrakow/ik_llama.cpp/commit/3d6e25c82db5510df483185b8a20f0ce01136dd7

+PP performance for those options:

+
+For my primary use case MLA-3 on is the best with nice PP and TG, it seems like though for tasks with very small PP and TG keeping context under 8K MLA-1 off is useful.

+Thank you for the quick find and fix.
