Bill, We run a massive CVS repository here at British Airways on AIX5.3. I have customised it significantly and it is running in a chroot jail rather than native for security reasons.
Running from /tmp is not something I have ever heard of, or would recommend (/tmp is for temporary files, not applications). CVS is not really CPU bound, but can be rather i/o bound when it comes to checking a number of items in/out. It also tends to use /tmp frequently as a temporary storage area. As your repository is also in /tmp I would be inclined to say that your i/o is out performing your disk capability. If I remember correctly, you can change the cvs temp area (during compile I think). but your most sensible thing would be to move your repository to a proper filesystem, preferably on a different physical disk. With regard to SSH being slow... If you are running OpenSSH, then try making it running it as a daemon rather than via inetd. That way it doesn't need to start for every connection as its already in storage. Hope this helps Iain "Bill V Vickery" <[EMAIL PROTECTED]> Sent by: [EMAIL PROTECTED] 26/09/2008 05:15 To [email protected] cc Subject Disk performance issue - CVS on AIX Anyone aware of a disk performance issue with CVS in AIX 5.2, where repository is located in /tmp and generating sufficient I/O load that it brings rootvg disks to 100%, with essentially zero throughput. System becomes unresponsive taking several minutes just to open a new ssh session. Any comments/advice would be appreciated.
