Java Httpurlconnection

[Somshekar C Kadam]

Hi Frantisek.

Thanks for your suggestion

I am seeing  on ARM lot many seconds wasted on this as shown below logs.
Where as in Intel I did not see a single reference, seems that is something
to do with it, need to  look further into it.

============
15033 08:10:27.254816 clock_gettime(CLOCK_MONOTONIC, {4286, 606936331}) = 0
15033 08:10:27.255070 clock_gettime(CLOCK_MONOTONIC, {4286, 607189947}) = 0
15033 08:10:27.255504 clock_gettime(CLOCK_MONOTONIC, {4286, 607662716}) = 0
15033 08:10:27.255924 clock_gettime(CLOCK_MONOTONIC, {4286, 608074100}) = 0
==================================
