Re: Data load is very slow in ignite 2.3 compare to ignite 1.9

[Alexey Kukushkin]

Specifying "swapPath" makes Ignite use memory mapped file to store data.
Memory mapped files are slower than "raw" RAM.

Remove "swapPath" setting to have same configuration as you had in Ignite
1.9 (data stored in off-heap RAM).
