Task #5682: tracking: smb performance issues
smb: large streams can cause large memory moves (memmove)
Added by Jeff Lucovsky about 3 years ago.
Updated almost 2 years ago.
Description
Large SMB streams can cause Suricata to move large chunks of memory (multi-tens of megabytes and higher) to make room for newly inbound packets. This seems to happen most often when there are gaps in the stream for which packets arrive later.
