From: Brad Volkin <bradley.d.volkin@xxxxxxxxx> For clients that submit large batch buffers the command parser has a substantial impact on performance. On my HSW ULT system performance drops as much as ~20% on some tests. Most of the time is spent in the command lookup code. Converting that from the current naive search to a hash table lookup reduces the performance impact by as much as ~10%.
I have another question - what about register lookups, do they come up in profiling as significant?
