hashcat command line version applies masks of incremental lengths, i.e. first try ?a than ?a?a, etc. Seems like ?a?a?a?a?a?a [6] is taking a long time (no surprise there) so add "--pw-min=8" to jump straight to 8 character. There's also a --pw-max option if you want to use that.
So try:
hashcat -m 0 -a 3 --pw-min=8 md5_hash.txt ?a?a?a?a?a?a?a?a
So try:
hashcat -m 0 -a 3 --pw-min=8 md5_hash.txt ?a?a?a?a?a?a?a?a
