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.
