Vladimir Ozerov commented on IGNITE-9996:
-----------------------------------------
I think that correct fix here would be to avoid lookups altogether. Instead, we
can remember "encrypted" flag of the cache group and pass it to related objects
(group context, cache context, BTrees, free lists). This way in most cases we
will be able to resolve proper page size without any lookups.
Even better - we can remember "realPageSize", not "encrypted".

> As per the latest reports we probably have a performance drop around 5-8% on
> write benchmarks in FSYNC mode. The cause needs to be investigated and fixed.
