Use more aggressive gc thresholds for a big speedup#18306
Merged
Conversation
In some cases gc was consuming a significant fraction of CPU, so run gc less often. Also tune gc very early, to run gc less during import time -- not sure if this has any significant impact, but in an unrelated project this was somewhat helpful. This makes incremental checking of torch 27% faster (based on 100 measurements), and also speeds up self check by about 10% (both incremental and non-incremental).

I simplified the PR, since tuning GC early before most imports seemed to make this a little bit slower instead of faster. |

This made incremental checking of torch 27% faster for me (based on 100 measurements), and also speeds up incremental self check by about 20% and non-incremental self check by about 10%. All measurements were on Python 3.13.
