Debian GNU / Linux kernel tuning for low latency on small files
E-mail servers, data base servers, file servers, web servers struggle to cope with LATENCY on accessing millions of small files under heavy concurrent load. Low latency is key factor to a good user experience. With the Debian GNU / Linux 6.x kernel tuning, combined with the previous article hints about XenServer I/O latency, tuning filesystems configuring multipath, and data storage, we reduced eighty-four times our virtual block device latency at our environment.
