-XX:+UseTLAB True on Solaris Use thread-local object allocation -XX:+AggressiveHeap Use for throughput applications with lots of CPUs and memory > 256MB. Turns on various flags, uses parallel scavenge collector for young generation, turns on Adaptive SizePolicy, increase sizes of TLAB and other...
Using a CLR finalizer results in the finalizer code being executed at some point after the object is out of scope (assuming that the code to release the lock is the finalizer), but not until the finalization thread is invoked on the object's finalizer. Clearly, this is not ...

To fully support concurrency and parallelism, a ContextVar should probably be used instead of a thread local. Owner agronholm commented Dec 27, 2023 Have you considered setting an attribute on the specific CBORTag object being hashed instead of using a global running_hashes set? It should be...
(GC) uses a per-thread allocation context and per-CPU segment of memory to increase throughput of memory allocations. This typically requires periodic rendezvousing with a central copy of data structures, and can sometimes require costs associated with copying and ensuring interesting bits of data ...
The problem below reproduce an issue that we have run into in production. We have a lot of ThreadLocal instances and quite a number of threads and we noticed very high latency for GC / CPU time spent collecting. The code below creates a ...

TLAB (Thread Local Allocation Buffer) Statistics This region shows Thread Local Allocation Buffer (TLAB) related JVM performance counters. To avoid the pointer contention in the Eden Space while allocating objects, each thread is given a private memory area where it does object allocation. This priv...
If the allocation is very critical to your scenario, you may consider having IEnumerable thread local object (e.g. List<>) which you can use for all subsequent calls on same thread. That might work, but the complexity of implementing such cache and the perf overhead required for cleaning ...
