Configuration

Lsm-rs is running on a single core. Memtier benchmark is used with following configuration: memtier_benchmark -h 127.0.0.1 -p 11211 -P memcache_binary -t 2 -c 6 --test-time=10 memtier_benchmark -h 127.0.0.1 -p 6379 -P resp3 -t 2 -c 7 --test-time=10

Baseline

Note: lsm-rs might not be isolated during testing which can cause high P99
