* Package name : proftpd-mod-fsync Version : 0.2 Upstream Author : TJ Saunders * URL : http://www.castaglia.org/proftpd/modules/mod_fsync.html * License : GPL-2 Description : On some kernels and/or filesystems, if there are files opened simultaneously for reading and writing, the buffer cache algorithms may cause the write I/O to swamp the read I/O, causing processes that are reading files to slow down because of buffer cache misses. The Linux 2.4 kernel, for example, suffers from this problem. The mod_fsync module attempts to prevent such bottlenecks by forcibly flushing to disk the buffers used for files open for writing after a certain number of bytes have been written (for example, after 128 KB has been written to a file). This prevents the buffer cache from being dominated by data from files being written, freeing up space for data for files being read. -- To UNSUBSCRIBE, email to debian-wnpp-requ...@lists.debian.org with a subject of "unsubscribe".
