I have a cluster of three machines, until yesterday worked on ES 1.4 and the last upgrade to 2.0 and now in shock ...
I do not know what to do.
What was once performed for 5 minutes now occupies 30-40 minutes ...
The last execution:
69,33s user c7,00s system 2% cpu 46: 44,24 total
That maxim that yesterday performed for 5 minutes.
Query will not change.
The sample is simple and update fields.
Sorry for my English.
