Operating Systems Linux Red Hat Disk performance problem on login Post 302478215 by dangral on Tuesday 7th of December 2010 11:02:14 AM

So I found the script that was causing the poor performance, but other symptoms have surfaced as well. Sometimes a simple 'ls' on a directory with 30 files will cause the disk to spin for 45 or so seconds while the box is under no other I/O load. Again, no error messages are apparent, and SMART data looks fine.

optimizing disk performance

I have some questions regarding disk perfomance, and what I can do to make it just a little (or much :)) more faster. From what I've heard the first partitions will be faster than the later ones because tracks at the outer edges of a hard drive platter simply moves faster. But I've also read in... (4 Replies)

NAME
cscope-indexer - Script to index files for cscope SYNOPSIS
cscope-indexer [-v] [-f database_file] [-i list_file] [-l] [-r] DESCRIPTION
This script generates a list of files to index (cscope.out), which is then (optionally) used to generate a cscope database. You can use this script to just build a list of files, or it can be used to build a list and database. This script is not used to just build a data- base (skipping the list of files step), as this can be simply done by just calling "cscope -b". Normally, cscope will do its own indexing, but this script can be used to force indexing. This is useful if you need to recurse into sub- directories, or have many files to index (you can run this script from a cron job, during the night). It is especially useful for large projects, which can contstantly have source files added and deleted; by using this script, the changing sources files are automatically handled. Currently, any paths containing "/CVS/" or "/RCS/" are stripped out (ignored). OPTIONS
-f database_file Specifies the cscope database file (default: cscope.out). -i list_file Specifies the name of the file into which the list of files to index is placed (default: cscope.files). -l Suppress the generation/updating of the cscope database file. Only a list of files is generated. -r Recurse into subdirectories to locate files to index. Without this option, only the current directory is searched. -v Be verbose. Output simple progress messages. SEE ALSO
