Would it be possible to store the binary trace record in the pstore
buffer instead of outputting text? I suspect that will both be faster
and less space.
I will try this and come back.
Hi Joel,
I removed trace_seq_putc and there is some improvement seen: 203 MB/s
# dd if=/dev/zero of=/dev/null status=progress
12207371264 bytes (12 GB, 11 GiB) copied, 60 s, 203 MB/s^C

24171926+0 records out
12376026112 bytes (12 GB, 12 GiB) copied, 60.8282 s, 203 MB/s
This seems good when compared to 190 MB/s seen previously.
If this is Ok, then I will spin v2 with changes suggested.
Thanks,
Sai
