Bug #3402
synchronization lags in dev
100%
Description
At least fo R client test, synchronization is taking wildly different amounts of time to sync objects. Looking at the cn-synchronization logs, I was able to use the timestamps in the identifiers to determine the delays. Attached is a spreadsheet with the line-item results. The delays are consistent across all 3 CNs, and break out into 4 basic groups:
a many-day delay group (looks like 2 periodic updates on Nov 4 and 9th)
a 22 minute delay group (one run of R tests)
a 2-4 minute range (normal?)
a 10 hour delay group (current)

fwiw: a recent top from cn-dev-ucsb-1 shows a somewhat high load comparatively:

I will review how the executor service should be configured and re-write some code.
