Isn't there somthing about largePageTables which must be enabled
in JAVA and also supported by OS for such huge heaps?
Just a guess.

It could be an issue with jdk 8 that may not be suitable for such large heaps.
Have more nodes with smaller heaps (eg 31 gb)

Hello, Solr!
We are having some performance issue when try to send documents for solr to
index. The repose time is very slow and unpredictable some time.
Solr server is running on a quit powerful server, 32 cpus, 400GB RAM, while 300
GB is reserved for solr, while this happening, cpu usage is around 30%, mem
usage is 34%. io also look ok according to iotop. SSD disk.
Our application send 100 documents to solr per request, json encoded. the size
is around 5M each time. some times the response time is under 1 seconds, some
times could be 300 seconds, the slow response happens very often.
"Soft AutoCommit: disabled", "Hard AutoCommit: if uncommited for 3600000ms; if
1000000 uncommited docs"
There are around 100 clients sending those documents at the same time, but each
for the client is blocking call which wait the http response then send the next
one.
I tried to make the number of documents smaller in one request, such as 20, but
still I see slow response time to time, like 80 seconds.
Would you help to give some hint how improve the response time? solr does not
seems very loaded, there must be a way to make the response faster.
