Hello everyone: I submitted a PR(https://github.com/apache/nuttx/pull/8755) to remove CRLF conversion in ramlog, which is unnecessary in ramlog and causes extra overhead. After removing the CRLF check, I will use memcpy instead of byte-by-byte copy, which will bring a large performance improvement.
Carriage returns are already discarded in libs/libc/stream/lib_syslogstream.c:152, and double checks will bring additional overhead. Here's how long it took me to test syslog 100 times: Original time: 1924us Remove CRLF time: 1918us Using memcpy time: 1094us Let me know if you find any other issues, thanks!
