Is anyone using the generational mode for the garbage collection in Lua 5.2.1?
After we ported our web application platform (Reflexis Flow) over to Lua 5.2 I ran several fairly simple scenarios to compare incremental gc to generational gc.
The difference seemed negligible. I was never able to tell from the performance data alone to which gc mode they belonged to... So, for the time being we decided to stick with the default (incremental) gc.
Having said that, all my tests were CGI-based [i.e. many short runs]. The outcome may well been very different for longer running processes. Perhaps someone using Lua 5.2 in games can relay their experiences?
