oblet - The Go Programming Language https://golang.google.cn/search?q=oblet
// put enqueues a pointer for the garbage collector to trace.
174 // obj must point to the beginning of a heap object or an oblet.
// maxObletBytes is the maximum bytes of an object to scan at 25 // once. Larger objects will be split up into "oblets" of at 26 // most this size. Since we can scan 1–2 MB/ms, 128 KB bounds 27 // scan preemption at ~100 µs. 28 // 29 // This must be > _MaxSmallSize so that the object base is the 30 // span base. 31 maxObletBytes = 128 << 10
// Oblets
121 //
122 // In order to prevent long pauses while scanning large objects and to
123 // improve parallelism, the garbage collector breaks up scan jobs for
124 // objects larger than maxObletBytes into "oblets" of at most
125 // maxObletBytes. When scanning encounters the beginning of a large
126 // object, it scans only the first oblet and enqueues the remaining
127 // oblets as new scan jobs.
