That reduces the snapshot size and thus the transfer time is reduced by ~100ms or 8%.

Before:
RESULT heap-snapshot: transfer-snapshot= 1494 ms
RESULT heap-snapshot: full-summary-snapshot-time= 5827 ms

After:
RESULT heap-snapshot: transfer-snapshot= 1378 ms
RESULT heap-snapshot: _buildEdgeIndexes= 5 ms
RESULT heap-snapshot: full-summary-snapshot-time= 5587 ms
