system.ini tweak

Post by seventoglory »

Here is a picture of my .ini folder. where whould I put the Irq tweak, I know that it should be put under the enh section but does that section end where the at the space between these two blocks of type or at the very bottom?

; for 16-bit app support

[drivers]
wave=mmdrv.dll
timer=timer.drv

[mci]
[driver32]
[386enh]
woafont=dosapp.FON
EGA80WOA.FON=EGA80WOA.FON
EGA40WOA.FON=EGA40WOA.FON
CGA80WOA.FON=CGA80WOA.FON
CGA40WOA.FON=CGA40WOA.FON

SCRNSAVE.EXE=C:\WINNT\system32\ssflwbox.scr
CGA40WOA.FON=CGA40WOA.FON

Looks as though your using XP or 2000, and neither of those utilize sys.ini for anything but 16bit stuff if that. Dont bother with that tweak.


A thought from John Navus
"The claim is that the tweak (IRQn=4096) improves network performance by allocating 4 megabytes of memory as a buffer for the IRQ (n) used by your network adapter. However:

The setting has no effect on actual memory allocation.
The setting does not actually affect network performance in carefully controlled tests. (Anecdotal reports are mixed, and unreliable due to Internet and system variabilities, particularly the effects of caching.)
There is no apparent evidence that there even is any such setting in Microsoft documentation.
Windows does not allocate buffer memory for IRQ's. (Buffers are the responsibility of device drivers, which allocate them by device, not by IRQ. On the PCI bus, a single IRQ can be shared by multiple devices.)
While it doesn't help, the good news is that (like TTL) this setting doesn't hurt (assuming you don't screw up your SYSTEM.INI file) -- Windows just ignores settings that it doesn't recognize.

Note: This may have gotten its start as confusion over the real SYSTEM.INI settings COMnIrq and COMnBuffer, which are used to control serial port IRQ assignment and buffering (the latter of which can help serial port throughput). But these settings pertain only to the standard Microsoft serial port driver, not to network adapters."
