Ruby 2.1's GC is worlds faster, for most applications-- especially with a minor amount of tuning. I saw GC time drop from 20ms to under 5ms (using new relic). Memory usage until GC has gone up a bit though.
I can only hope, and have good reason to after 2.1, that future improvements are so good.
Where using more than one instance would be desirable (I'm not trying to over optimize-- I swear! ;-_-). I suppose one server can go pretty f#€£ing far. But all the clustering requires a license (~$12k per server for start ups?) unless the code which uses it is GPL or AGPL (I think?).
Anyone who wants to explain the AGPL in layman terms would be greatly appreciated. Or specially Neo4j's application of it. To me, it seems cost prohibitive for lean startups, of one or two people.
Again, they've said contact 'em-- so it may be case by case. I could just be worrying about non-existent problems.
I tried Titan and Orient, I didn't find either as nice as Neo4j to use in my code. Though Neo4j, for me, was much more difficult to setup and use as a cluster (at the time).
... And more on topic, I'm about to install Cayley!
I'm curious as to how you're dealing with the licensing costs, as they shut down most hopes I had. Granted, Neo4j said they had a "startup" license but due to family issues i never followed up. Still seems a bit extreme to me for the price, but I also (at the time) couldn't really compare it to much else.
And on the topic of Cayley... I'm stoked. I'll give it a try tonight. Easy to use, and graph databases, haven't really gone hand in hand for me.
Due to the varying size of the releases; it's hard to compare them to each other.
While a buggy turd, 10.0, was amazing at the time and blew windows out of the water. It was phenomenal by comparison.
In the end I ended up voting for 10.8 because it works damn well-- was a painless upgrade process, even with all my dev tool installed. That has definitely not always been the case.
I can only hope, and have good reason to after 2.1, that future improvements are so good.
... Ruby just gets better by the year, I love it!
