Hello,
Kindly guide/help us on this. I already shared the requested files.
There's nothing that jumps out at me in the config.
You should configure caches ... it won't help with commit time but it is
likely to speed up queries unless every query your Solr receives is
entirely unique. Be careful that you don't set autowarmCount too high
... that slows down commits. On a big install I managed, I set
autowarmCount on the filterCache to 4 ... and commits could still
sometimes take 15 seconds to complete.
As I said before, 100 milliseconds is COMPLETELY unrealistic. I would
personally set autoSoftCommit maxTime to at LEAST 30000. Jan's
recommendation is at least 1000 ... I think that's also unrealistic.
Depending on a bunch of things including how big your index is, 5
seconds may not be all that bad for a commit time.
Now for the 20 questions:
What OS do you have this running on? How much physical memory is in the
machine? Is it running anything other than Solr? What is the Solr heap
size? Are you running more than one Solr instance on a single machine?
How big are all the index cores on a single machine? Looking for Max
Doc, Num Docs, and on-disk size ... all of these are found on the core
overview in the admin UI.
There may be more questions depending on what the answers to those
questions reveal.
I am working my way towards getting a screenshot of the process list.
