The analyzer threads have use additional queues for capturing packets to each disk or each disk cluster. Storage devices like HDDs and SSDs do not offer a constant write rate and have sudden write slowdowns. Please read the performance guide for the ring buffer [[Ring_Buffer_Configuration_Guide#Performance]] on how to adjust the options for high capturing performance. | The analyzer threads have to use additional queues for capturing packets to each disk or each disk cluster.

The two generic solutions are to increase the buffer and to use filter rules. Both will reduce the number of bytes that are written to the disk. | The two generic solutions are to increase the buffer and to use filter rules. Both will reduce the number of bytes that are written to the disk. | ||
