The analyzer have software queues for each disk or each disk cluster. Storage devices like HDDs and SSDs do not offer a constant write rates and have sudden write slowdowns. Please read the performance guide for the ring buffer [[Ring_Buffer_Configuration_Guide#Performance]].
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 2 generic solutions are to increase the buffer and to use filter rules. Both will reduce the load of bytes that are written to the disk.
