Performance in solr7.5

Hi All,

I am facing performance issue while searching. It took 10mins to get the
results.i have 2 shard and each shard having 2 replicas.80M documents and
index size in each shard is  2T.

Any suggestions?

Thanks

Look at your I/O stats. My bet is that you’re swapping like crazy and your CPU is relatively idle.

2T of index on two machines is probably simply too much data on too little hardware.

Consider stress testing your hardware gradually, see:
