Logstash performance regression in JSON encoding
Logstash 8.14.1 fixed a bug in the JSON encoding of strings containing non-unicode data #15833.
The fix introduced a performance regression that has since been solved with #16313 and included in Logstash 8.15.0.
There is no workaround for this issue, please upgrade to Logstash 8.15.0 or later.
