Hi! Since a few weeks I'm using an encrypted /home partition, which is a LUKS partition in a logical partition. (Not wrapped in LVM or similar.) I'm experiencing annoying latency problems when writing data in my home, I cannot eg. flawlessly listen to music while synchronising mails or surfing the web as kMails writes to to Offline Imap store or Konqueror's writes to the web cache will cause many clearly noticeable interruptions in the audio stream every few seconds at least. These latency problems are also more-or-less clearly visible in other applications which display animations or similar, eg. gkrellm. No such problems exist even during heavy IO load on unencrypted partitions, no matter if "native" or LVM2 partitions. Is there any way to debug these problems or does anyone have an RTFM pointer to further documentation which may help to solve these problems? Hardware + software used: * Centrino Notebook with Core2 Duo T7200 (2 * 2 GHz cores) CPU * 2 GB RAM * Toshiba MK3252GSX SATA HDD, 5400 U/Min, 320GB, > 60MB/sec read performance according to "hdparm -t -T" * Linux Kernels 2.6.2[234] (Debian SID Kernel images) * LUKS details: Version: 1 Cipher name: aes Cipher mode: cbc-essiv:sha256 Hash spec: sha1 Payload offset: 1032 MK bits: 128 The command "/usr/sbin/bonnie++ -b -n 3" will make it just impossible to listen to music if executed on an encrypted partition, and will not influence music playback if issued on a non-encrypted partition. I hope there's a simple solution for the problems I'm experiencing as I love listening to music while using my computer and hate having to stop it every time I check for mails or do anything else which writes more than a few bytes to my "home" directory...
