Perfetto plugin - Memory optimizations and table renaming #48

Closed KyleStorck closed 3 years ago

KyleStorck commented 3 years ago

Made some memory optimizations to help improve the sluggishness in WPA when viewing large traces. Memory optimizations reduce memory usage by about 50%. UI is more responsive now. Optimizations include

Used string interning on the high-count string fields
Switched the variable length argument fields from List to string[]
Changed bunch of longs to ints. These are mostly ID fields. Confirmed they are int or smaller within Perfetto

Table renaming

Removed redundant "Perfetto" from all tables and column config names
Added column configs that graph by StartTime instead of duration for GenericEvents
