How to control CPU usage

Is there any configuration to control to max amount of CPU manticore can use?

We are experiencing high CPU usage (constant 90%+ by the searchd processes) on our server, since manticore 4.2.

there was a change of how work items got utilized by threads at 4.2

you could set at daemon config options

searchd.threads as described here Manticore Search Manual: Searching > Options to lower cpu threads that your box has

or set searchd.max_connections as described here Manticore Search Manual: Server settings > Searchd to limit amount of clients daemon will process
