The bigger the process, the longer takes the fork.
Oracle DB processes might be a little better because they use a large portion of "shared memory".

Since also Solaris is from Oracle, you can consider analysis method/tools from Oracle.
Also OS patches often boost performance.

Also you can monitor your system.
E.g. on the command line do
Code:
vmstat 2

you can likely see a bottle neck: a big value in the "b" column means a slow disk, a big value in the "r" column means too much work for the CPU.
If you have a slow CPU, you can look how CPU time is distributed between "sy"s=kernel and "us"er=processes, and hopefully something is left for "id"le. (These values are in percent and sum up to 100.)
If you have a slow disk, you can break down this further with
Code:
iostat -D 2

or with the OS disk names (but long names are truncated)
Code:
iostat -nD 2

Looking for
Code:
netstat | grep 'TIME[_]WAIT'

is a good idea because these processes are waiting for the client to re-open the connection, they cannot be used for another client.
If there are too many processes in TIME_WAIT it can improve by tuning it down, say from
Code:
ndd /dev/tcp tcp_time_wait_interval

60000 reduce it to 30000
Code:
ndd -set /dev/tcp tcp_time_wait_interval 30000
ndd /dev/tcp tcp_time_wait_interval

NAME
irsend - basic LIRC program to send infra-red commands SYNOPSIS
irsend [options] DIRECTIVE REMOTE CODE [CODE...] DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
irsend LIST DenonTuner "" irsend SEND_ONCE DenonTuner PROG-SCAN irsend SEND_ONCE OnkyoAmpli VOL-UP VOL-UP VOL-UP VOL-UP irsend SEND_START OnkyoAmpli VOL-DOWN ; sleep 3 irsend SEND_STOP OnkyoAmpli VOL-DOWN irsend SET_TRANSMITTERS 1 irsend SET_TRANSMITTERS 1 3 4 irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S" FILES
/etc/lirc/lircd.conf Default lircd configuration file. It should contain all the remotes, their infra-red codes and the corresponding timing and wave- form details. DIAGNOSTICS
If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics: "irsend: could not connect to socket" "irsend: Connection refused" (or "Permission denied"). SEE ALSO
The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory. lircd(8), mode2(1), smode2(1), xmode2(1), irrecord(1), irw(1), http://www.lirc.org. irsend 0.9.0-pre1 October 2010 IRSEND(1)
