	I posted a article "Is there a program to test BUS CLOCK SPEED?"
yesterday and got some reponses through e-mail. For those of you who are
interested, I have not received any hint about "a program", nor have I solved
the puzzle about the "2" in CLK2I/5. There are some interest comments about 
the bus speed though. It seems that some people believe an increased bus 
speed will not improve the overall performance too much but only cause trouble.
So, I did some benchmark tests to see if there are performance improvements.

	Test machine: 486DX/50, 256k cache, 8MB RAM.
	Peripherals : 16-bit IDE controller card, Seagate 3283A HD,
		      Diamond Stealth vidoe card.
	Test speed  : 8.33Mhz, 10Mhz, 12.5Mhz.

	Test results:

	1. EGA/VGA Text Mode Tests (PC Magazine Labs Benchmark 6.0):

		 i) 10Mhz   : 35% faster than 8.33Mhz in average.
		ii) 12.5Mhz : 61% faster than 8.33Mhz in average.

	2. EGA/VGA Graphics Mode Tests (PC Magazine Labs Benchmark 6.0):

		 i) 10Mhz   : 15% faster than 8.33Mhz in average.
		ii) 12.5Mhz : 23% faster than 8.33Mhz in average.

	3. Graphics Winmark (PC Magazine Labs WinBench 3.1):

		 i) 10Mhz   : 14% faster than 8.33Mhz in average.
		ii) 12.5Mhz : 23% faster than 8.33Mhz in average.

	4. Hard disk maximum thruput (Comptest 2.57):

		 i) 10Mhz   : 16% faster than 8.33Mhz.
		ii) 12.5Mhz : 36% faster than 8.33Mhz.

	5. Hard disk data transfer rate (Norton Utilities 6.0):

		 i) 10Mhz   : 18% faster than 8.33Mhz.
		ii) 12.5Mhz : 23% faster than 8.33Mhz.

	I understand there are potential problems associated with the
improvements on system performance. But, what are these problems? Does 
anybody have experiments against the "significant" performance boost?
Thanks.
