Description Tomas Hurka 2007-10-29 11:14:24 UTC 
Opening large heap dump is much slower on Linux than on other systems. This was tested on heap dump with 19M instances.

Comment 1 Tomas Hurka 2007-10-29 11:15:55 UTC 
Opening same heap dump on MacBook Pro took about 4 minutes.
Comment 2 Tomas Hurka 2007-10-29 14:51:14 UTC 
Several improvements were implemented to speedup opening of heap dump. With those improvements we were able to open
above mentioned heap dump in 17 minutes on the same Linux machine.
