We are planning to use System V message queue as primary IPC for our project. We would like to know the following information 1. Performance impact of using message queues 2. We are changing the system configuration to take the max message queue size of 2 MB instead of default 16K. Will this have any impact on system performance. 3. We have a design where a sender process pumps 1MB of data into message queue continuously and the reader reads each message and processes the same. We are planning to use message queue between this sender and receiver process.Is message queue a right choice for this ? If not, what are the drawbacks ? 4. In our system, we are creating 8 message queues of size 500KB each and a single 2MB message queue. In the worst case all the message queues are always filled up. Will the performance be affected in this case. -Thanks ________________________________________________ Get your own "800" number Voicemail, fax, email, and a lot more http://www.ureach.com/reg/tag -- Kernelnewbies: Help each other learn about the Linux kernel.
