Thanks for your help, to be honest, I haven't tried so far. Can we leave it at 2.0.0 target for now? If I run into problems, I'll ask here! ---------------------------------------- Feature #6047: read_all: Grow buffer exponentially in generic case https://bugs.ruby-lang.org/issues/6047#change-33374 Author: MartinBosslet (Martin Bosslet) Status: Assigned Priority: Normal Assignee: MartinBosslet (Martin Bosslet) Category: core Target version: 2.0.0 In the general case, read_all grows its buffer linearly by just the amount that is currently read from the underlying source. This results in a linear number of reallocs, It might turn out beneficial if the buffer were grown exponentially by multiplying with a constant factor (e.g. 1.5 or 2), thus resulting in only a logarithmic numver of reallocs. I will provide a patch and benchmarks, but I'm already opening this issue so I won't forget. See also https://bugs.ruby-lang.org/issues/5353 for more details. -- http://bugs.ruby-lang.org/
