LogMgrFileSize

HKLM\SOFTWARE\Microsoft\MSMQ\Parameters

Data type	Range	Default value
REG_DWORD	0x0 - 0xFFFFFFFF bytes	0x600000 (6 MB)

Description

Determines the size of the Log Manager file. The size of this file affects its maintenance and Message Queuing's performance. Message Queuing performs checkpoints (saves the current log entries) when the log file occupies more than half of the space allocated for it. If the value of this entry is too small, Message Queuing takes checkpoints too frequently, diminishing overall performance. If the file is too large, it consumes unnecessary disk space.

Do not change the value of this entry. An inappropriate value can interfere with logging and with the operation of Message Queuing.
