Math check: it's not 0.5s/2000, it's 0.5ms/2000, which is around a
quarter of a microsecond, which seems plausible
It also doesn't sound like a huge performance hit: you can do 4,000,000
of them in a second, which seems pretty small compared to the overall
overhead of Thrift (not to mention any business logic).

That last answer in the comment chain just asserts that this is the cost of
autoboxing. It doesn't actually describe any measurements.
I think that is a made-up number. I find it very hard to imagine that it
costs hundreds of microseconds to box or unbox an integer (0.5 s / 2000).

the last answer indicate that auboxing 2000 Integer add 0.5 ms... yes it's
not much but if you are doing a lot of such operation it starts to adds up
especially on a server side web apps/web services.
Interesting. Would love to see if that measured up the same way in Thrift.
