erlang 发布了一个新的小版本R13B01

主要是一个bug fix版本，也有一些SMP方面的增强:

Erlang/OTP R13B01 has been released. R13B01 is a service release for R13B. There are mostly error corrections but also some new functions. Some highlights in the R1301 release are: Communication between Erlang nodes over the Erlang distribution protocol is mademore parallel , a new atom cache protocol is introduced as part of this. This allows better performance on SMP and multi-core systems. Improved SMP concurrency for ETS tables. Several processes can now perform truly concurrent updates of different records in the same table. Two new options are added to open_port - spawn_executable and spawn_driver . See the erlang manual for details. New functionality in ETS to transfer ownership of a table. Leex, a lexical analyzer generator for Erlang, has been added as a complement to yecc in the Parsetools application. Read the readme file for R13B01 for details. Download the new release from the download page .

gen_server:call/2,3 will be somewhat faster if the calling process has a many messages in its message queue.


这个看上去也不错

这个非常小的优化 。
