why BV32 Encoding takes ten times as long as decoding?

Hello,

I use BroadVoice32OpenSource.v1.2.zip to test encoding and decoding,On windows10 or ARM Nordic nRF52840，

using 16bit 16Khz Continuous audio，And has been converted bin2c array.（Normal sound can be played through I2S）

Simplified code：

Reset_BV32_Encoder((struct BV32_Encoder_State*)enc_state);
Reset_BV32_Decoder((struct BV32_Decoder_State*)dec_state);

//for(int i=0;i<10000;i++) or one times
BV32_Encode((struct BV32_Bit_Stream*)enc_bs, (struct BV32_Encoder_State*)enc_state, data);
BV32_BitPack(oPackedStream, (struct BV32_Bit_Stream*)enc_bs);

//for(int i=0;i<10000;i++) or one times
BV32_BitUnPack(oPackedStream, (struct BV32_Bit_Stream*)dec_bs);
BV32_Decode((struct BV32_Bit_Stream*)dec_bs, (struct BV32_Decoder_State*)dec_state, data);

I get the result as shown in the figure.(the same on J-Link RTT Viewer log)
see the png and MSVC project code.

My question，why BV32 Encoding takes ten times as long as decoding?

thanks
