    Virtual Table performance optimizations in 5.6

    I've been working on optimizing Virtual Table (VT) performance in 5.6 specifically with section relationships.

    In Lianja 5.5 and below sections that are bound to VTs in desktop apps (not web or mobile) build temporary indexes to be able to relate sections. This works fine with small to medium sized tables but is not satisfactory with large tables.

    In Lianja 5.6 (next release) I have optimized these section relationships to use requery() which has resulted in a dramatic performance improvement. It also allows visual drag and drop of virtual tables (drag for form sections and shift+drag for grid sections) to be significantly faster thereby speeding up development.
