Hi I've made some local performance testing
First I tried with https://github.com/memcached/mc-crusher but it seems it doesn't calculate any statistics after the load runs. The results below are from https://github.com/RedisLabs/memtier_benchmark 1) Text ./memtier_benchmark --server XYZ --port 12345 -P memcache_text ARM64 text ========================================================================= Type Ops/sec Hits/sec Misses/sec Latency KB/sec ------------------------------------------------------------------------- Sets 985.28 --- --- 20.02700 67.22 Gets 9842.00 0.00 9842.00 20.01900 248.83 Waits 0.00 --- --- 0.00000 --- Totals 10827.28 0.00 9842.00 20.02000 316.05 X86 text ========================================================================= Type Ops/sec Hits/sec Misses/sec Latency KB/sec ------------------------------------------------------------------------- Sets 931.04 --- --- 20.06800 63.52 Gets 9300.21 0.00 9300.21 20.32600 235.13 Waits 0.00 --- --- 0.00000 --- Totals 10231.26 0.00 9300.21 20.30200 298.66 2) Binary ./memtier_benchmark --server XYZ --port 12345 -P memcache_binary ARM64 binary ========================================================================= Type Ops/sec Hits/sec Misses/sec Latency KB/sec ------------------------------------------------------------------------- Sets 829.68 --- --- 23.46500 63.90 Gets 8287.69 0.00 8287.69 23.56100 314.75 Waits 0.00 --- --- 0.00000 --- Totals 9117.37 0.00 8287.69 23.55200 378.65 X86 binary ========================================================================= Type Ops/sec Hits/sec Misses/sec Latency KB/sec ------------------------------------------------------------------------- Sets 829.32 --- --- 23.63600 63.87 Gets 8284.10 0.00 8284.10 23.58600 314.61 Waits 0.00 --- --- 0.00000 --- Totals 9113.42 0.00 8284.10 23.59100 378.48 Text is faster on the ARM64. Binary is similar for both.
