The user reported that compiling a single source file on mips64el takes about 2214 times longer than on the host, which is way more than the 24-33x slower for other targets. + +First, I remember that different CPU architectures have varying performance in emulation. MIPS64 might not be as optimized in QEMU as some of the others. Maybe the emulator doesn't handle certain instructions as efficiently, leading to slower execution. + +I also recall that some emulators use JIT (Just-In-Time) compilation to speed things up by translating guest code into host code on the fly. If mips64el isn't leveraging JIT effectively, that could explain the slowdown. Or perhaps there are issues with how QEMU is configured for MIPS compared to other architectures. + +Looking at the command lines provided, I notice that the other targets use "-smp 8" to set up multiple CPUs, but mips64el doesn't support SMP. The test compiles a single file, so maybe the lack of multi-threading isn't the main issue here since it's only using one CPU. But without SMP, there could be other limitations. + +Another angle is that the guest OS might not be properly configured for optimal performance. Maybe Debian 12 on MIPS64EL isn't as optimized or has different kernel parameters that affect performance compared to the other guests. + +I should also consider whether the host's CPU architecture plays a role. If the host is, say, an x86_64 machine and the emulated targets are more similar (like ppc64 or s390x), perhaps they have better support for binary translation or JIT. MIPS might be handled differently, leading to worse performance. + +Maybe there's a specific issue in QEMU's mips64el implementation that causes it to emulate much slower than others. It could be bugs in the instruction decoding, lack of optimizations, or issues with how interrupts or other system calls are handled. + +I think this problem is more related to the system-mode emulation because it involves how the entire OS runs within QEMU, including CPU handling and device emulation. Since performance is so poor across a basic compilation task, it's likely a broader issue with how QEMU is emulating the MIPS64EL architecture rather than something specific to user-mode applications. +</think> + +system \ No newline at end of file |
