973 JDCT_IFAST: less accurate integer method [legacy feature]976 JDCT_FASTEST: fastest method (normally JDCT_IFAST)979 was measured in minutes. Thus, JDCT_IFAST provided noticeable982 milliseconds, and thus the performance benefits of JDCT_IFAST are much984 instructions, JDCT_IFAST and JDCT_ISLOW have similar performance. On985 other types of CPUs, JDCT_IFAST is generally about 5-15% faster than990 levels above 90, however, the difference between JDCT_IFAST and992 JDCT_IFAST incurs generally about a 1-3 dB loss in PSNR relative to994 JDCT_IFAST with quality levels above 97.
