Hi,
It is a good idea to
use heap tables for vpopmail query-s ? MyISAM tables for UPDATES, and HEAP for
selects (they will be created from MyISAM)? I wanna to minimalize the disk
subsystem impact. System is always waiting for disks(big load, can even reach
20-25). What is the ideal maximum concurrent conncetion limit with mysql
?
I want to put the
temp directories (spamassasin, clamd, other scanners) to ramdisk. What to
use:
1. ramdisk, fixed
size (set with kernel parameter), with ext2, looks like a "real" disk, with real
filesystem
2. tmpfs, with
maximized ramsize, eating always as many ram what is needed. cons ? What is the
price for this "freedom" ?
(can I use tmpfs on
a debian server for the main /tmp ?) I can spend 512 or even 1024 Mb
ram for ramdrives, or tmpfs.
I need every idea,
or solution, how can I reduce the disk usage on the system. I want to keep only
what is necessery. I will turn of mail logging via syslog (deamontools is
doing a great job logging mails, why waste the needed disk i/o power for
syslog), other things ?
What if I put qmails
queue to ramdisk (or tmpfs ramdisk) ? (memory cards ? are good enough
?)
Peter
