--- Comment #18 from Jacek Ablewicz <abl at biblos.pk.edu.pl> ---
For some reason, deep copying of MARC frameworks structures with clone() is
insanely slow:

- clone() from the Clone module: 62 ms !!!
- clone() from Clone::Fast: 21 ms
- Storable dclone(): 16.9 ms
- Storable thaw(freeze()): 17.0 ms
- fetching framework from DB directly (caching disabled in GetMarcStructure()):
36.6 ms

If I replace clone() with Storable dclone() in Koha::Cache, search speed is
back to normal. Well, almost - looks like fetching the framework directly from
L2 cache is still faster (12.8 ms, L2 = memcache) then getting a clone from L1
cache.
