--- Comment #8 from Harald Anlauf <anlauf at gmx dot de> ---
No lag with 4.8.0 (or 4.7.x) on same machine:

==8545== HEAP SUMMARY:
==8545==     in use at exit: 0 bytes in 0 blocks
==8545==   total heap usage: 41 allocs, 41 frees, 40,007,187 bytes allocated
==8545== 
==8545== All heap blocks were freed -- no leaks are possible


So it's actually a regression.
