Mapping speed of STAR is very different for similar bam #2227

I want to remap some database bam files to ribosome regions. However, I find the mapping speed of different bam files is very different.

According to the file tempLog.progress.out, the mapping speed changes from 10 M/hr to 300 M/hr, which is very big difference. So I am wondering whether you have some any ideas on this difference? Will the way bam file was sorted influence the result? Thanks very much in advance!
