Summary: Switch both Transport::write() overloads (ByteRange and IOBufQueue) to use writeChain instead of writev/write. This enables the zero-copy (MSG_ZEROCOPY) code path in AsyncSocket::writeChainImpl, which checks zeroCopyEnabled_, isManaged(), and the enable threshold before adding MSG_ZEROCOPY to individual writes. The old writev/write path bypassed writeChainImpl entirely, so zero-copy decisions were never evaluated even when zero copy was enabled on the socket. For the IOBufQueue overload, this also avoids an intermediate std::vector<iovec> allocation from getIov(). For the ByteRange overload, wrapBuffer creates an unmanaged IOBuf so isManaged() returns false, meaning MSG_ZEROCOPY won't be added (which is correct since ByteRange data may point at stack memory).

HHVM

HHVM is an open-source virtual machine designed for executing programs written in Hack. HHVM uses a just-in-time (JIT) compilation approach to achieve superior performance while maintaining amazing development flexibility.
HHVM should be used together with a webserver like the built in, easy to deploy Proxygen, or a FastCGI-based webserver on top of nginx or Apache.
Installing
If you're new, try our getting started guide.
You can install a prebuilt package or compile from source.
Running
You can run standalone programs just by passing them to hhvm: hhvm example.hack.
If you want to host a website:
- Install your favorite webserver. Proxygen is built into HHVM, fast and easy to deploy.
- Install our package
- Start your webserver
- Run
sudo /etc/init.d/hhvm start - Visit your site at
http://.../main.hack
Our getting started guide provides a slightly more detailed introduction as well as links to more information.
