I will have to look up somewhere, I took the heap dump and analyzed it but can't recall it right now but I believe a TGT may be between 1.5KB to 2.5KB. This highly depends on how many times a TGT is used as each use is being tracked in a HashMap inside a TGT. I am not too worried about ST as it is short lived and meant to be used in shor time and deleted after use or through clean up job.
My calculation was that with 2 GB heap size, JVM could hold roughly atleast 500k to 1 million TGTs.
