It can now handle 240k SQLite write QPS at 3ms 99 percentile latency. We're still working out the kinks since it's brand new. But we've got this running in production already! |

*NSYNC
*NSYNC is a library providing scalable synchronization primitives. The following packages are provided:
THIRD_PARTY_NSYNChasnsync_muwhich doesn't depend on malloc().THIRD_PARTY_NSYNC_MEMhas the rest of *NSYNC, e.g.nsync_cv.
The origin of this code is here:

NSYNC uses the Apache 2.0 license. We made the following local changes:
-
Write custom
nsync_malloc_()somalloc()can use *NSYNC. -
Rewrite
futex()wrapper to support old Linux kernels and OpenBSD. -
Normalize sources to Cosmopolitan style conventions; *NSYNC upstream supports dozens of compilers and operating systems, at compile-time. Since Cosmo solves portability at runtime instead, most of the build config toil has been removed, in order to help the NSYNC source code be more readable and hackable.
