我在 MIPS 中针对 uCLibc 库和许多其他动态共享库构建了一个复杂的可执行程序。该程序运行良好，但加载时间超过 20 秒，当我通过“strace”观察它时，我发现它不断打开和关闭一些基本库，如 libm、libc、libgcc 等。请在下面找到日志：

open("/lib/libc.so.0", O_RDONLY)        = 3
fstat(3, {st_mode=S_IFREG|0755, st_size=477720, ...}) = 0
close(3)                                = 0
open("/lib/libgcc_s.so.1", O_RDONLY)    = 3
fstat(3, {st_mode=S_IFREG|0644, st_size=213564, ...}) = 0
close(3)                                = 0
open("/lib/libc.so.0", O_RDONLY)        = 3
fstat(3, {st_mode=S_IFREG|0755, st_size=477720, ...}) = 0
close(3)                                = 0
open("/lib/libm.so.0", O_RDONLY)        = 3
fstat(3, {st_mode=S_IFREG|0755, st_size=96616, ...}) = 0
close(3)                                = 0
open("/lib/libgcc_s.so.1", O_RDONLY)    = 3
fstat(3, {st_mode=S_IFREG|0644, st_size=213564, ...}) = 0
close(3)                                = 0
open("/lib/libc.so.0", O_RDONLY)        = 3
fstat(3, {st_mode=S_IFREG|0755, st_size=477720, ...}) = 0
close(3)                                = 0
open("/lib/libdl.so.0", O_RDONLY)       = 3
fstat(3, {st_mode=S_IFREG|0755, st_size=9504, ...}) = 0
close(3)                                = 0
open("/lib/libgcc_s.so.1", O_RDONLY)    = 3
fstat(3, {st_mode=S_IFREG|0644, st_size=213564, ...}) = 0
close(3)                                = 0
open("/lib/libc.so.0", O_RDONLY)        = 3
fstat(3, {st_mode=S_IFREG|0755, st_size=477720, ...}) = 0
close(3)                                = 0
open("/lib/libc.so.0", O_RDONLY)        = 3
fstat(3, {st_mode=S_IFREG|0755, st_size=477720, ...}) = 0
close(3)

我确信这种持续的打开和关闭动作会减慢我的程序速度，我尝试在 /etc 下创建 ld.so.cache 但它不起作用，它仍然需要 20 秒才能加载。有人有想法吗？谢谢。
