Zitat von Andrew Bourgeois <and...@demmel.be>:
Hello What does "Speed up disk updates with a large (64MB) persistent write cache." mean (source: http://www.postfix.org/TUNING_README.html)? Does this talk about the "dirty ratio" or is it something else? Google didn't help me on this one. Thanks in advance! Best regards Andrew
"This allows disk updates to be sorted for optimal access speed without compromising file system integrity when the system crashes"
That's why you need a *persistant* cache, to not loose mail and get decent performance.
