[OSRM-talk] osrm-extract taking hours to complete

I'm currently extracting the planet PBF (~31 GB), and it's been running
for hours. I notice in the "Running OSRM" wiki page, it says " On a Core
i7 with 8GB RAM and (slow) 5400 RPM Samsung SATA hard disks it took
about 65 minutes to do so from a PBF formatted planet", which is making
me wonder why it's taking so long on our server. Below are some example
[info] Parsing finished after 3584.35 seconds
[extractor] Erasing duplicate nodes ... ok, after 319.091s
[extractor] Sorting all nodes ... ok, after 3632.87s
[extractor] Building node id map ... ok, after 2025.29s
[extractor] Confirming/Writing used nodes ... ok, after 1096.24s
[extractor] Sorting edges by start ... ok, after 2000.08s
Some stxxl errors were outputted as I set the disk size to 100GB
thinking it was enough - but I didn't think it would cause such
slowdowns as this, considering extracting the Europe PBF takes hours
also without the stxxl errors.
Intel Xeon CPU E5-1650 v3 @ 3.50GHz (hex-core with HT)
64 GB RAM @ 2133 MHz
2 TB Western Digital Enterprise 7200 RPM hard drive
At the moment, disk IO is averaging around 35-40 MB/s R/W (~90%).
Anyone have any ideas as to what might be going on? Or is it normal to
take this long without an SSD?
Thanks in advance.
