Hi, Geraldo sends test results for LBAcache and element sizes: - mscdex - format - load LBAcache with 6 MB (buf 24) (default element size: 4k) - OR load smartdrv 12288 /x /u /e:4096 (this is 6 MB as well! A bug in smartdrv makes it assume 8k element size for the element count calc -> lower count makes cache size smaller -> asking for 12 MB at 4k element size means actually 6 MB. /x /u is no CD-ROM and no delayed write caching) Then do: d:\window~1\installa /c /ie /im /iv /nr (all kinds of "ignore ... do not load internal cache module ...") In the end, SMARTDRV is something like 0.5 of 15 minutes faster and the result of LBAcache /INFO or SMARTDRV /S respectively is:
(PS: stacks=0,0 files=100 ... himem and emm386 loaded... efficient cd driver) SMARTDrive 5.02 with 1536 elements of 4k each: 87,469 cache hits and 104,988 cache misses LBAcache with 6 MB and 4k element size: 71599 read hits, 57672 read misses, 36150 write hits, 381603 write misses I think SMARTDrv counts in elements or in calls to "int" 25/26 here. LBAcache oounts in sectors when creating the statistics. SMARTDrv has 45% of 192k SOMETHINGS hit ratio, LBAcache has 55% of 129k sector read hit ratio and 8% of 417k sector write hit ratio (low because a Windows install means writing most files ony once, for which a cache does not really help). It would be interesting to compare this to - same with SMARTDRV 6144 /x /u (with default 8k element size) - LBAcache with other element sizes (compile time option, explained in the binsel*.asm files) Do you know in what units the SMARTDRV statistics are counted? Thanks to Geraldo for testing, interesting result although the statistics count in different units :-). (BCCing him...) Eric. PS: I got a report that the FAT32 386 build dot bat does not work (too long command line) with Turbo C++ but works fine with Turbo C on the same computer.
