TEST_HEADER id = $HopeName$ summary = Compare variety.hi/he and variety.wi performance language = english END_HEADER From variety.hi and variety/he: | | .desc: This variety is intended to have as much checking and | telemetry as possible, but with no significant performance | overhead as compared to variety.wi. | | .slow: A "significant performance overhead" is a slow-down of | more than 10% in any typical operation. | | .slow.just: The figure 10% was chosen because it is at a level | that an interactive user would not observe. | To test that varieties hi and he meet these requirements, compare them with wi by running tests and measuring times. Tests to run: - client application (Dylan, ScriptWorks &c) - MMQA_test_function!{77,78,79,80}.c and others It's not quite clear in the quote above whether "a slow-down of more than 10%" means a slow down in memory-managament time, or a slow down in total application time. I take it to refer to a slow-down in memory-management time, given a typical pattern of allocation, freeing, &c. Therefore if, say, Dylan goes 5% slower with variety.hi than variety.wi, I will complain because the MM takes less than 50% of Dylan's time, so the MM overhead must be more than 10%. Test is passed if varieties hi and he are within 10% of performance of variety.wi. rit 1998-03-13
