posix_fadvise()

Hello list. As far as documentation goes, some sense may be presumed in libpcap calling posix_fadvise() with POSIX_FADV_SEQUENTIAL. This way the OS would be able to adjust the buffers better to read the .pcap file. Does anybody have any practical experience with posix_fadvise() to comment if the gain is ever visible with present day hardware and OSes? -- Denis Ovsienko _______________________________________________ tcpdump-workers mailing list tcpdump-workers () lists tcpdump org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
