Hi Erick,
As suggested, I did try nonHDFS solr cloud instance and it response looks to
be really better. From the configuration side to, I am mostly using default
configurations and with block.cache.direct.memory.allocation as false. On
analysis of hdfs cache, evictions seems to be on higher sid
Hi Arun,
It is hard to measure something without affecting it, but we could use debug
results and combine with QTime without debug: If we ignore merging results, it
seems that majority of time is spent for retrieving docs (~500ms). You should
consider reducing number of rows if you want better r
Hi Emir,
Please find the response without bq parameter and debugQuery set to true.
Also it was noted that Qtime comes down drastically without the debug
parameter to about 700-800.

Hi Erick,
Qtime comes down with rows set as 1. Also it was noted that qtime comes down
when debug parameter is not added with the query. It comes to about 900.
Thanks,
Arun

That does not come as a surprise. Your collections would normally b
Hi Arun,
This is not the most simple query either - a dozen of phrase queries on several
fields + the same query as bq. Can you provide debugQuery info.
I did not look much into debug times and what includes what, but one thing that
is strange to me is that QTime is 4s while query in debug is 1.3
Well, 15 second responses are not what I'd expect either. But two

Hi Erick,
Thank you for the quick response. Query time was relatively faster once it
is read from memory. But personally I always felt response time could be far
better. As suggested, We will try and set up in a non HDFS environment and
update on the results.
Thanks,
Arun

Does the query time _stay_ low? Once the data is read from HDFS it
should pretty much stay in memory. So my question is whether, once
Solr warms up you see this kind of query response time.
Have you tried this on a non HDFS system? That would be useful to help
figure out where to look.
And given
Hi All,
I have been using Solr for some time now but mostly in standalone mode. Now
my current project is using Solr 6.5.1 hosted on hadoop. My solrconfig.xml

querying seems to really slow. Can anyone help me with few poin
