Hi Eric, Thanks for the reply. It is very useful for me.
For point 1. : I do need 10 core and it will go on increasing in future. I have document that belongs to different workspaces , so the 1 workspace = 1 core ; I cant go with one core. Currrently having 10 core but in future the count may go 40+. For point 2.: Currently I have not given any thought on it , but yes I think in future I may have to go for the master/slave setup For point 3: the current cache size for document cache , filter cache and query cache is 512 for each the ramBufferSizeMB size is 512M. Shall I reduce the same to 128M? For point 4: I didnot get you why should I use SolrJ with Tika? Do you mean sending the new/updated documents to Tika for reindexing? Then I am already doing it using data-config. I have written the query in data-config in way that it takes the path of updated/new documents. Thanks in advance! Regards, Abhijit Multiple webapps will not help you, they're still on the underlying memory. In fact, it'll make matters worse since they won't share resources. So questions become: 1> Why do you have 10 cores? Putting 10 cores on the same machine doesn't really do much. It can make lots of sense to put 10 cores on the same machine for *indexing*, then replicate them out. But putting 10 cores on one machine in hopes of making better use of memory isn't useful. It may be useful to just go to one core. 2> Indexing, reindexing and searching on a single machine is requiring a lot from that machine. Really you should consider having a master/slave setup. 3> But assuming more hardware of any sort isn't in the cards, sure. reduce your cache sizes. Look at <ramBufferSizeMB> and make it small. 4> Consider indexing with Tika via SolrJ and only sending the finished document to Solr.
