Here is the raw list of all possible ini settings that can go in your /etc/hhvm/php.ini or /etc/hhvm/server.ini file. Not all of them are useful, many are redundant, tons are useless (or only useful at Facebook scale) and many others are useful. There is lots of cleanup work to do here, but for now you get a sorted list, sorry.
This list is just the HHVM-specific options. Many standard PHP options are also supported by HHVM, meaning the same thing that they do to PHP5. So your favorite option may just work out of the box with the same name.
| INI Setting | Documentation | Default |
|---|---|---|
| hhvm.admin_server.password | A password required for all requests to the admin server, other than the index. Is passed to the request as the auth request var. |
empty string |
| hhvm.admin_server.port | The port the admin server should listen on. If set to 0, the admin server is not started. | 0 |
| hhvm.admin_server.thread_count | The number of threads the admin server should use. | 1 |

The translation cache stores the JIT'd code. It's split into several sections depending on how often the code is (or is expected to be) executed.

|---|---|---|
| hhvm.jit_a_size | Size in bytes of main translation cache. | 62914560 (60 MB) |
| hhvm.jit_a_cold_size | Size of cold code cache. Code that is unlikely to be executed is deemed cold. (Recommended: 0.5x hhvm.jit_a_size) | 25165824 (24 MB) |
| hhvm.jit_a_frozen_size | Size of extremely cold code cache. Code that is almost never executed, or executed once and then freed up, is deemed frozen. (Recommended: 1x hhvm.jit_a_size) | 41943040 (40 MB) |
| hhvm.jit_a_hot_size | Size of hot code cache. (Enabled only in RepoAuthoritative mode) | 0 |
