What version are you running? There have been several changes since that thread was started related to the synchronization speed issue (MAX_SEND_SIZE among them). It is recommended to use recent versions. > And just one question fullsync is only option for HAST replication at tim= e > of writing, so could HAST perform at 100MB/sec in this mode, and when we > expect memsync and async to be released? Synchronization is run in background by synchronization thread and hardly depends on replication mode. Anyway, HAST from CURRENT, STABLE/9 and STABLE/8 supports all three modes. The async mode was merged to stable branches in Jan 2012, and reached 8.4 and 9.1 (I am not sure about the later, one needs to check). The memsync mode was merged in Apr 2013, after 8.4 freeze, so there is no release that would contain it yet. --=20 Mikolaj Golub
