That syscall trace is useful. It turns out that the emulation for lseek(2) still resides in the brand library, rather than the kernel module. While it may not represent the entire differential in performance, it's a place to start. I've filed OS-5583 to that end.
That would explain the correspondingly high number of brand syscalls (one per lseek) when I traced non-lx calls.
I'll keep an eye out for the fix to OS-558. If you have something you want testing, please ask.
