search for: 8kbytes

hi all, the stacksize required for encoder and decoder are 32Kbytes and 16 Kbyes respectively. i changed it to 20Kbytess and 8Kbytes and it seems to work. but need to trim further. can someone point me in the right direction to further reducing the stack size? thanks! cheers, tk

Hi all, I recently started with Xen (3.1.0) on my new server running Ubuntu Gutsy (7.10) and I''m experiencing very poor network performance on my domU''s. Since my colo provider offers me a /28 of routed public IPs next to one interconnection IP to their routers, I built a Xen configuration as described in http://www.debian-administration.org/articles/360 (a routed

...e? [As a side-note, you''re probably wondering why we don''t just use O_DSYNC when opening the file, and then just write(2) to it. The reason for this is because it''s very slow on UFS for large buffers - effectively linear with the number of pages crossed, or about 6ms per 8KBytes on an otherwise idle SCSI disk on SPARC. The good news is that this is very fast on ZFS - on the same disk, about 7ms constant for up to 64KBytes, and about 20ms constant for 256KBytes. However this is still a bit slower than the msync(3C) approach on UFS] Thanks in advance. -- Philip Beevers m...

With today''s build, my domain 0 crashes during boot when it tries to bring eth0 up (it''s an E100). cb->prev (eax) is NULL in e100_exec_cb() (e100.c:827). Just from code inspection, I don''t see how this can be. e100_alloc_cbs() was just called, which looks like it should have correctly linked up all the cb->prev/cb->next pointers. It happens regardless of

Maybe this question is a little stupid, but please help me. I am a newbie to Xen. When I tried to create a new domain "domain 1", I followed the Yan-Ching CHU''s guide on :installing quick file systems for new domains in Xen 1.2". But when I do "xc_dom_create.py -Dvmid=1", Xen seems to start to boot with some normal bootup information, but right after several
