Would the Disk bottleneck affect the mail flow?
As well all know, yes that will “affect the slow or affect” the mail flow
Reason:
Every message that is received by an SMTP gateway is saved to a disk.
- With a default message size of 50 KB, about 7 to 8 disk writes occur for each message processed by the SMTP gateway.
- This behavior is expected. Generally, SMTP performs 7 disk writes for every message queued that is smaller than 32 KB.
- An SMTP gateway’s write buffer is 32 KB. Therefore, messages that are larger than 32 KB require an additional disk write for every 32 KB.
For example, a 100-KB message requires 10 disk writes to save the message in the queue.than 1 GB of memory.
it is good to run EXTRA to check the disk bottleneck and blame the “Third party” with a proof J
