Memory Managers and String Building

One thing interested me since I started reading Eric’s series on string concatenation performance – how would different memory managers compare in a multi-threaded scenario. Today I decided to spend an hour finding out…

edit 18/11: the tests were run with debug mode, which affected TTextWriter very negatively (TWOBS is also affected a negatively, but less, and StringBuilder and Trivial aren’t affected much).  I’ll be repeating tests with more memory managers and in more stable conditions in the next few weeks.


Boosting Work Classes with a mini Object Pool

gearsWork and processing classes are typically short-lived, created to perform one form of processing or another then freed. They can be simple collections, handle I/O of one kind of another, perform computations, pattern matching, etc.

When they’re used for simple workloads, their short-lived temporary nature can sometimes become a performance problem.
