On a related note, the log4j-perf module has experimental source code and a
benchmark for a custom formatter. This formatter can only handle the
%d{ABSOLUTE} format (HH:mm:ss.SSS) which allows it to take some shortcuts and
be 5-7x faster than SimpleDateFormat in single-threaded tests.
However,
That seems like a good idea.

For this purpose I would think that would cause a bunch of problems.

How abt providing the date formatter as part of log4j itself ( on the lines
of FastDateFormatter from commons-lang) ?

Is it not possible to just use ThreadLocal? Is that not safe enough or does
it waste too many resources?

The converter uses a SimpleDateFormat which is not thread safe and so is
synchronized. I am sure there might be minor optimizations that could be done
to this
What I would do is modify DatePatternConverter to
a) use Java 8’s java.time.format.DateTimeFormatter if running on Java 8
b) use Joda T
Hi Mohit,
What version and can you provide stack dumps?
You can attach files to a new JIRA issue.
Thank you!

I am using log4j2 and I am seeing almost all the threads
momentarily getting blocked on
org.apache.loggin.log4j.core.pattern.DatePatternConverter class. Is this
expected?
