I need to issue a correction to the above: it turns out the key difference was the -z
parameter.
When doing gzip compression on the output, skewer's CPU usage maxes at around a third (3 full cores vs 9) of when not using -z
please disregard the following and see the followup comment - speed issues tracked down to output compression option
When using
-m any
I can max out 8-9 cores (Xeon X5670 @ 2.93 GHz).However, using the exact same adapter file (2 adapters), in either
-m head
or-m tail
mode my CPU usage pegs at < 300%. This means up to 8 times longer runtime.In addition, I am going to file a probably related bug in that 5 prime adapters are not found and removed when run in
-m any
mode, while they are in the slower but apparently more effective-m head
mode.
