This patch adds a small typename cache to ObjectClass. This allows caching positive casts within each ObjectClass. Benchmarking a PPC workload provided by Aurelien, this patch eliminates every single g_hash_table_lookup() happening during the benchmark (which was about 2 million per-second). With this patch applied, I get exactly the same performance (within the margin of error) as with --disable-qom-cast-debug. N.B. it's safe to cache typenames only from the _assert() macros because they are always called with string literals. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> |
