Signing service performance appears to be very badly degraded

Summary

The Orbit BND builds jar-sign all the jars:

https://ci.eclipse.org/orbit/job/orbit-simrel-maven-bnd/

This appears to take roughly 4 times longer:

The Platform's I-builds also appears to be much slower now:

I'm not sure it's the same cause, but for the BND build, jar-signing was already the dominant cost.

Steps to reproduce

The BND build is a good test case.

What is the current bug behavior?

Signing appears to be 4 times slower.

What is the expected correct behavior?

Not so much slower.
