[英]Mono GC max-heap-size isn't documented. Is it safe to use in production?
已記錄了文檔,這是獲取文檔的一種方法: export
無效的MONO_GC_PARAMS
,啟動mono
:
export MONO_GC_PARAMS=xxx
mono sample.exe
並獲得幫助:
Warning: In environment variable `MONO_GC_PARAMS': Unknown option `xxx`. - Ignoring.
MONO_GC_PARAMS must be a comma-delimited list of one or more of the following:
max-heap-size=N (where N is an integer, possibly with a k, m or a g suffix)
soft-heap-limit=n (where N is an integer, possibly with a k, m or a g suffix)
nursery-size=N (where N is an integer, possibly with a k, m or a g suffix)
major=COLLECTOR (where COLLECTOR is `marksweep', `marksweep-conc', `marksweep-par', 'marksweep-fixed' or 'marksweep-fixed-par')
minor=COLLECTOR (where COLLECTOR is `simple' or `split')
wbarrier=WBARRIER (where WBARRIER is `remset' or `cardtable')
stack-mark=MARK-METHOD (where MARK-METHOD is 'precise' or 'conservative')
[no-]cementing
evacuation-threshold=P (where P is a percentage, an integer in 0-100)
(no-)lazy-sweep
Experimental options:
save-target-ratio=R (where R must be between 0.10 - 2.00).
default-allowance-ratio=R (where R must be between 1.00 - 10.00).
如您所見,列出了max-heap-size
,而不是在Experimental Options
。 所以我說這很安全。
它記錄在mono手冊頁中 :
設置堆的最大大小。 該大小以字節為單位指定,並且必須為2的冪。 后綴“
k',
m”和“ g”可分別用於指定千字節,兆字節和千兆字節。 限制是托兒所,主要堆和大對象堆的總和。 一旦達到限制,應用程序將在嘗試分配時收到OutOfMemoryExceptions。 由於內部碎片,不能以max-heap-size設置全部內存范圍來滿足單個分配。 默認情況下,禁用堆限制,並且GC將嘗試使用所有可用內存。
