Apply minutely diffs performance

How long does it generally take to download and apply 1 minutely diff?  Is it longer than a minute?  smile

Running apply_osc_to_db.sh, I see output that does not include the update ID...

Reading XML file ... finished reading nodes. Flushing to database ...... done.
Reading XML file ... finished reading ways. Flushing to database ...... done.
Reading XML file ... finished reading relations. Flushing to database ....... done.
Update complete.

This takes wayyyyy longer than 1 minute.  More like ~10 mins.  Might this script be combining minutely diffs and applying more than 1 at a time? 

Is there a technical reason the update ID is not displayed?

Re: Apply minutely diffs performance

The script can combine multiple diffs in one run. Check apply_osc_to_db.log file contents, it's telling you the exact diffs that are being processed (updating from ... updating to   ----> update complete) along with the respective timestamps.

Overall performance may depend on a number of factors. SSD is mandatory these days.
