### Description

These are the results of calling `benchmark64`

### Usage

    data(benchmark64.data)

### Format

The format is: num [1:16, 1:6] 2.55e-05 2.37 2.39 1.28 1.39 ... - attr(*, "dimnames")=List of 2 ..$ : chr [1:16] "cache" "match(s,b)" "s %in% b" "match(b,s)" ... ..$ : chr [1:6] "32-bit" "64-bit" "hashcache" "sortordercache" ...

### Examples

    data(benchmark64.data)
    print(benchmark64.data)
    matplot(log2(benchmark64.data[-1,1]/benchmark64.data[-1,])
    , pch=c("3", "6", "h", "s", "o", "a")
    , xlab="tasks [last=session]"
    , ylab="log2(relative speed) [bigger is better]"
    )
    matplot(t(log2(benchmark64.data[-1,1]/benchmark64.data[-1,]))
    , axes=FALSE
    , type="b"
    , lwd=c(rep(1, 14), 3)
    , xlab="context"
    , ylab="log2(relative speed) [bigger is better]"
    )
    axis(1
    , labels=c("32-bit", "64-bit", "hash", "sortorder", "order", "hash+sortorder")
