Hi, Since myself working for Embedded platform mainly for SH4. We usually take webkit nightly from webkit.org. We are facing the critical performance issues in Sun Spider bench mark results with latest webkit nightly. Please find our Sun Spider result for SH4-7105(with JIT & debug mode)for various revisions below, Webkit-r74228 - 21,764 ms string(6876) date(4300) Webkit-r85429- 21,545 ms string(7941) date(4734) Webkit-r86784- 28,544 ms string(11553) date(7060) According to us performance is getting reduced gradually in newer revisions. Also we found that date & String related operation's avg.execution time is gradually increasing(See the above observation). The above problem is not only for SH4 platforms also same issues in X86 too.(With WinLauncher-cairo-curl build) Regards, Vicky.

Did you say "with JIT & debug mode"? Debug mode is not a valid performance testing setup.

Hi Geoffrey Garen, >>Did you say "with JIT & debug mode"? Debug mode is not a valid performance testing setup. I will comeback with Non Debug Sun Spider result.
