Operating Systems Solaris Rsync quite slow (using very little cpu): how to improve its speed? Post 303018387 by priyadarshan on Tuesday 5th of June 2018 09:49:13 AM
Old 06-05-2018
No, I have been running tests on a new system, with just OS install,
Code:
NAME    SIZE  ALLOC   FREE  CKPOINT  EXPANDSZ   FRAG    CAP  DEDUP  HEALTH  ALTROOT
 rpool   476G   136G   340G        -         -     0%    28%  1.00x  ONLINE  -

After advice on this forum, I simplified testing, now only on local SSD.

I created a 10G file (with urandom, to avoid zfs caching), and had following results (tested many times, best result reported):

Code:
### cp to same SDD

root@omniosce:~# time cp random.bin random1.bin

real    0m5.671s
user    0m0.134s
sys     0m4.974s

root@omniosce:~# time rsync -a random.bin random2.bin

real    1m25.644s
user    2m24.261s
sys     0m14.273s

### rsync'ing to same SDD with Joyent pkgsrc rsync

root@omniosce:~# time /opt/local/bin/rsync -a random.bin random1.bin

real    0m31.302s
user    0m40.634s
sys     0m13.994s

The last result is very close to what I get with FreeBSD on exact same hardware.

So, it seems to me, a possible reason could lie in OmniOS core rsync.

NAME
RoPkg::Rsync::LogParser - a rsync log parser class SYNOPSIS
#!/usr/bin/perl use strict; use warning; sub main { my $lp = new RoPkg::Rsync::LogParser( type => 'client' ); $lp->Parse('/tmp/debian-log.txt'); } main(); Short description RoPkg::Rsync::LogParser is a class used to parse (for the moment) client side rsync logs. Using this class you can extract the transfered files, symlinks created, directories, total number of files, transfered bytes, speed of transfer etc. LogParser support list filter trough probes (used by many projects to verify the mirrors). The primary use of this class is inside Simba, but can be used without problems in any other project who needs a rsync client log parser. METHODS
new(hash) Constructor of the class. When creating a new class instance you must provide the type of log: client or server . For the moment only the client parsing routines are defined. Log($raw_log) Get/Set the raw rsync log. With no parameters, the get behaviour is selected. If a parameter is present (and valid) the method acts as a Set method. Probes(@probes_list) Get/Set the raw probes list. If no parameter is present, the method returns the number of probes defined (0 if none). If a list of probes is given, the list is added to the existing list of probes. Parse($filename) Parse a rsync client log. If no filename is specified, the method parses the log previsiously set with Log() method. Please take extra care with the filename. If it does not exists, or is not a file a exception will be raised (Param::Wrong and File::Open). Files() In scalar context returns the number of transfered files (filtered by probes list). In list context, returns the list of transfered files. RealFiles() In scalar context returns the number of transfered files. In list context, returns the list of transfered files. Deleted() In scalar context returns the number of deleted files (filtered by probes list). In list context, returns the list of deleted files. RealDeleted() In scalar context returns the number of deleted files. In list context, returns the list of deleted files. Speed() Returns the speed (as reported by rsync [in bytes/sec]) of the transfer. Size() Returns the size of the synced content. TransfData() Returns the total number of bytes transfered during the sync session Symlinks() In scalar context returns the number of symlinks (filtered by probes list). In list context, returns the list of symlinks. RealSymlinks() In scalar context returns the number of symlinks. In list context, returns the list of symlinks. PREREQUISITES
RoPkg::Utils requires perl 5.008 or later and RoPkg::Exceptions class. From CPAN, you need the Scalar::Util module. At build time Test::More is required for tests (if you don't plan to use the tests ignore this dependency). SEE ALSO
