zixuanweeei commented on issue #14713: [WIP]MKLDNN RNN Inference Integration(fp32 LSTM and vRNN with tanh and relu) URL: https://github.com/apache/incubator-mxnet/pull/14713#issuecomment-493766252 I re-evaluated the performance with MKLDNN commit 41bee20d7eb4a67feeeeb8d597b3598994eb1959 on local Skylake-8180 with 1 Sockets and 28 cores. Here is the result. ### Layer=1 bidirectional = False |API|MKLDNN = 0 (sample/sec)|MKLDNN = 1(sample/sec)|speedup| |---|-----------------------|----------------------|-------| |FusedLSTM|289 |682 |2.36x | |FusedvRNN with tanh|733 |1408 |1.43x | |FusedvRNN with relu|1074 |1375 |1.28x | ### Layer=5 bidirectional = True |API|MKLDNN = 0 (sample/sec)|MKLDNN = 1(sample/sec)|speedup| |---|-----------------------|----------------------|-------| |FusedLSTM|28 |65 |2.32x | |FusedvRNN with tanh|70 |149 |2.13x | |FusedvRNN with relu|94 |147 |1.56x |
