imporving performance of slicing on matrices and S4 their derivatives
Dear list. It is a known issue that accessing slots of S4 objects and in particular accessing .Data slots is slow in R. However, what surprises me are two things demonstrated in the code below (runnable with 'inline', my times are in the comments): - copying data out of a large 3x1e7 .Data slot into a matrix can be easily made 3-4 times faster than accessing a .Data slot which I believe

[PATCH] vhost-net: utilize PUBLISH_USED_IDX feature
With PUBLISH_USED_IDX, guest tells us which used entries it has consumed. This can be used to reduce the number of interrupts: after we write a used entry, if the guest has not yet consumed the previous entry, or if the guest has already consumed the new entry, we do not need to interrupt. This imporves bandwidth by 30% under some workflows. Signed-off-by: Michael S. Tsirkin <mst at

Converting integers to chars i.e 1 to "01"
Hello! I am producing a set of images and I would like them to be sorted by names I give. I was able to produce my names and add integer to them. That is easy. But my problem lies in sort of file from this process: figure_10.png figure_11.png figure_12.png ... figure_1.png figure_20.png ... So I would like to convert integers to something like 01 if upper limit for this conert is 10 or 001

[PATCH V3 0/3] basic busy polling support for vhost_net
This series tries to add basic busy polling for vhost net. The idea is simple: at the end of tx/rx processing, busy polling for new tx added descriptor and rx receive socket for a while. The maximum number of time (in us) could be spent on busy polling was specified ioctl. Test A were done through: - 50 us as busy loop timeout - Netperf 2.6 - Two machines with back to back connected mlx4 - Guest
