If I launch a search in search head, can I make it possible to let each distributed search job in every indexer run on muilti cpu cores? Since my indexer has 24 cores, so only one cpu doing the job is really slow! My splunk version is 4.3.
Each search and subsearch uses 1 CPU during the duration of the search. You could break you search big search in to manageable sub searches. Look at improving searches query. Read Exploring Splunk Serach processing language Primer and Cookbook. Order of operations and distilling fields might help.
