<pre>I think this has been fixed for a while. We experienced slowdown of many lld
linked programs a few months ago, but various testing says it has been fixed.
One significant thing was the redundant ld-linux-x86-64.so.2 DT_NEEDED entry in
DSOs (D55902/r349849). In the case of 5000+ DSOs, the extra DT_NEEDED in every
DSO directly depended by the executable made glibc ld.so tens of seconds slower
at startup. glibc has O(n^2) string comparison in several places.
The bloom filter Shift2 was improved in D55971/r349966</pre>
