What happend when I use gatk HaplotypeCaller, it become very slow.

When I use gatk HaplotypeCaller, I got this error:

WARN IntelPairHmm - Intel GKL Utils not loaded
WARN PairHMM - ***WARNING: Machine does not have the AVX instruction set support needed for the accelerated AVX PairHmm. Falling back to the MUCH slower LOGLESS_CACHING implementation!

I can run HaplotypeCaller normally before, since I got this , the progress became twice slower. I am sure my CPU support AVX instruction.
